2002 Maserati Spyder – Tuning The M138 Engine

2002 Maserati Spyder

2002 Maserati Spyder Tuned By Smokey's Dyno

A customer recently brought his 2002 Maserati Spyder down to our shop to get some information on tuning and what gains we could expect to get out of it.  Typically on a Maserati tune, and on most naturally aspirated cars we tend to see an average gain of around 8-10% at the wheels.  We also suggest installing a high flow BMC air filter as well to help the engine breathe better.

Toyota Tundra TRD Supercharged “Flex Fuel”

TRD Supercharged Toyota Tundra

2010 TRD Supercharged Toyota Tundra Built By Smokey's Dyno

The 5.7L Toyota Tundra is a very good truck right off  the showroom floor.  The Tundra’s power is rated at 381 hp and 401 lb·ft from the factory.  Toyota began selling a bolt-on TRD Supercharger kit for the 5.7-liter V8 Tundra during June 2008. Power output is increased to 504 hp (376 kW) and 550 pound-feet.  This TRD kit is only made for the non-flex fuel trucks.  This is where the aftermarket world steps in.

We recently had a customer come to us and ask us to find a way to make the TRD Supercharger work with his flex-fuel Toyota Tundra.  Knowing already that this is not a factory option supported by toyota, we began to do some research on the matter.  What we found was that the actual supercharger kit would physically fit on the truck, but that there was no way to make the factory computer work with it.  We did a little digging to find a company called Unichip that makes a “piggyback” style ecu controller that could control the fuel the new supercharged truck would need and the spark that would need to be taken out at wide open throttle conditions.  We contacted Unichip and presented them with our situation.  To our surprise, we found that their controller would work with our Tundra.  We were informed by unichip that they no longer offered a plug and play system and that we would have to wire in the spider harness they offer to our factory wire harness ourselves.  Knowing that we have the ability to wire in the spider harness we instantly bought the entire tuning package from them to test it out.

The first thing we did was strap the Tundra to our AWD Superflow dyno and made a baseline dyno pull.  The results were good with the truck producing 318HP and 355TQ at the rear wheels in stock form.  These numbers are right on par with the factory ratings at the engine.  After unloading the truck from the dyno we began the tear-down process.  The process of installing the TRD supercharger was extremely straight forward.  We followed the instructions and ran into no problems with it.  This kit comes complete with some of the best instructions weve ever seen included with a supercharger kit.  One thing to consder is that the actual supercharger itself is extremely heavy.  We used 3 guys to set it in place to make sure no one got injured.  This could be a 2 person job if there was not a 3rd person but we would not recommend to go that route.  Our customer contacted us during this install and asked if we knew of any other aftermarket parts we could install to make a little more power.  We decided to go with  Doug Thorley long tube headers to increase the power and make a deeper sound to enjoy.  If you have never installed long tube headers on a Tundra, I would suggest having a professional shop like ourselves do it as it is a very difficult job to do.  We decided to go with the adapter plates from Doug Thorley as well because we wanted to maintain the rear cats for emissions and keep the fuel smell down.

Now that the TRD Supercharger, Doug Thorley long tube headers and Unichip controller are installed we can get to tuning.  The Unichip controller does come with a base map made for the TRD non-flashed truck which is a good place to start.  We loaded up the map and started the truck.  The Tundra came to life and sounded amazing!  The idle was good and everything seemed to be behaving.  We then proceeded to loading the Tundra back onto the dyno.  Now it was time for some fun.  After making some partial test pulls, we found that our truck needed some more fuel added to be safe.  We made our tweaks to the ecu and attemted our first full dyno pull.  The truck screamed to life, we crested 6000 rpm’s making 8lbs of boost and put down a respectable 430HP and 437TQ.  We adjusted the fuel table and tweaked the timing a bit and made our final pull to see an amazing 458HP and 467TQ!  Thats a gain of 140HP and 112TQ.  Not bad for a factory TRD Supercharger and long tube header install.

In conclusion, we are very happy with the TRD kit, Unichip  and the Header kit we used for this project. This truck can no longer run flex fuel and that is perfectly fine with the customer.  The best part of all is that the factory computer works in perfect harmony with the Unichip with no check engine lights what so ever.

Corvette Z06 – “Unleashing” The Power Of The LS7

2007 Corvette Z06

2007 Corvette Z06 Tuned By Smokey's Dyno

When it comes to raw torque, GM got it right with the 2007 Corvette Z06.  The new Corvette Z06 arrived as a 2006 model in the third quarter of 2005. It has a 7.0 L version of the small block engine codenamed LS7. At 427.6 cubic inches, the Corvette Z06 had the largest small block ever offered from General Motors. Because of the Corvette’s former use of 427 cubic-inch big blocks in the late-1960s and early 1970s, the LS7’s size was rounded down to 427 cubic inches. Official output is 505 bhp and has a 0-60 mph time of 3.8 seconds and a top speed of 198 mph.

This particular Corvette Z06 came to Smokey’s Dyno and Dynoed in at 435 rear wheel horsepower and 439 rear wheel torque.  The customer informed us that he was ready for more power and wanted the car to sound meaner than it already did so we called our friends at Kooks Custom Headers.  Kooks was happy to help and sent us their full package including:

Long Tube Equal Length Stainless Headers

Stainless X Pipe with High Flow Cats

We got right to work installing the parts.  The installation was very straight forward and fit incredibly well on this car.  Kooks really did their homework on the Z06 vette exhaust.  With the addition of the Kooks setup it was time to hit the Dyno rollers again and see the improvement.  To our surprise, the Z06 picked up 13 rear wheel horsepower and 15 rear wheel torque for a total of 448 HP and 4407 TQ.  It was clear from the graph that the car would benefit from a custom tune so we got right to it and made up a base tune for the Z06.  After some fine tuning we were able to achieve an amazing 48 HP and 35 TQ Gain at the wheels!  The Z06 was now a fire breathing street machine.  Check out the final Graph!  It’s simply amazing what can be done with a Z06 with a set of Headers, X-Pipe, and Smokey’s Dyno custom Corvette Z06 dyno tune.

BMW 328xi – Tuning the N52 Engine

BMW 328xi

2007 BMW 328xi Tuned By Smokey's Dyno

Its hard to beat an all wheel drive BMW during the winters in Northeast Ohio, the BMW 328xi is great at this.  This particular vehicle is a equipped with a 3.0L inline six N52 engine, all wheel drive, and an automatic transmission.  Any time you see a newer body style 1, 3, or 5 series BMW there is a good chance it has the N52 naturally aspirated 3.0L six.  Stock BMWs aren’t slouches when it comes to performance, but theres always room for improvement.

The horsepower and torque gains for our BMW 328xi Tune are quite impressive, with noticeable improvements to throttle response and everyday drivability.  There are not a lot of companies offering significant performance gains for the N52 engine.  Most companies focus on the performance engines found in the M series or twin-turbo N54 engine used in 335, 535, and now almost every other series.

BMW 328xi Dyno Graph

BMW 328xi Dyno Graph (Tune vs. Stock)

Stock horsepower of the 328xi was measured at 162 HP/ 152 ft.lbs torque.  After letting the BMW ECU adapt to the new tune for over 100 miles the car was re-run on the dyno to measure the increase in wheel horsepower and torque.  An impressive increase was seen across the board as you can see above.  We achieved a gain of 22 HP and 28ft.lbs torque on an otherwise 100% stock car.  Put the car in sport mode and there is a night and day difference in the performance of the 328xi after being tuned.  Couple the tune with a few aftermarket bolt on performance parts and the N52 engine can really come to life.

The owner of this BMW 328xi called to let us know that this car was performing great during everyday driving, highway cruising, and even track day events.   He also followed up to let us know that city and highway driving fuel economy numbers have improved.  Even though fuel economy numbers may vary with driving style most people notice an improvement.  For more information on this BMW Tune please contact Jesse Yorty.

Subaru WRX – Flat Four Power

2005 Subaru WRX

2005 Subaru WRX Tuned By Smokey's Dyno

When this vehicle came into our shop it was very interesting to work on.  The customer brought his 2005 Subaru WRX in with only a Magnaflow exhaust on it.  He had purchased a Tanabe Downpipe and wanted us to install it on his vehicle before we tuned it.  We love opportunities like these because it allowed us to do several pulls on the vehicle to see what gains can be achieved from adding different parts.  Below is the stock graph for this vehicle.

2005 Subaru WRX Stock Dyno Graph

2005 Subaru WRX Stock Dyno Graph

This car made 186 horsepower and 184 torque with only a Magnaflow exhaust on it.  We made one other dyno pull on it in stock form to verify our results were consistent.  We then put the Subaru on our lift and proceeded to remove the factory downpipe.  After a few cuts and scrapes from the factory heat shield we had the stock downpipe off and the brand new Tanabe downpipe installed.  After we installed the Tanabe we strapped the WRX back on the dyno and proceeded to do another pull, watching air/fuel closely, to see what gains were achieved from the new downpipe.  Below is the Dyno graph comparing the stock pull and the downpipe pull.

2005 Subaru WRX Dyno Graph

2005 Subaru WRX Dyno Graph (Stock vs. Downpipe)

This car was now making 204 horsepower and 199 torque after the downpipe was installed.  Since our installation was done it was time to get to tuning.  The gains we were able to get out of this car were nothing short of awesome.  On all the Subaru’s we tune here at Smokey’s Dyno we tend to see extremely good gains on cars with a few bolt-ons and a tune.  But the gains we achieved on this specific vehicle were a bit unexpected due to it only having a downpipe and exhaust.  Below is the graph comparing stock, downpipe, and downpipe-tune.

2005 Subaru WRX Dyno Graph

2005 Subaru WRX Dyno Graph (Stock vs. Downpipe vs. Downpipe-Tune

This  Subaru WRX Tune ended up making 242 horsepower and 260 ft. lbs of torque for a total gain of 56 horsepower and 76 torque.  These cars typically respond very well to tuning and can get rid of a good deal of the lapse in power at lower rpm. Below is the final stock vs. tune power difference.

Tuning A Maserati Quattroporte – Power And Response

Maserati Quattroporte On Smoke's Dyno

Maserati Quattroporte On Smokey's Dyno

I received a call one day by a gentleman with a 2005 Maserati Quattroporte.  He was referred to us by a local company we do business with often and wanted information on a tune for his vehicle.   The 2005 Maserati Quattroporte comes equipped with a Ferrari/Fiat built 4.2 liter engine from the factory.

Maserati Quattroporte Engine

Maserati Quattroporte Engine Tuned By Smokey's Dyno

This engine in stock form produces 394 Horsepower and 333 foot pounds of torque at the flywheel.  On this particular vehicle the power ended up being 344 horsepower and the torque ended up at 290 foot pounds, about a 10-15% loss through the drivetrain.  The Maserati Quattroporte tuning increases horsepower, torque, and throttle response all the way across the board.  On the later year Quattroporte’s we also have the ability to increase the exhaust volume.  From the factory these vehicles come with valves in the mufflers that quiet the exhaust volume after the car shifts out of 2nd gear.  When we tune these vehicles we can program the computer to command that these valves stay open.  This will make the vehicle sound more aggressive and sportier (like a Ferrari engine should sound) while cruising around town or passing on the freeway.  After tuning this car we were able to increase the power to to 376 Horsepower and 327 Torque.  In the image below you can see the gain was prevalent throughout the entire RPM range.  Along with the tune we also installed a BMC air filter to increase air flow to the engine.

BMW 535xi = HUGE Potential

BMW 535xi

BMW 535xi At Smokey's Dyno

We recently got a customer in who had a 2008 BMW 535xi.  We chatted for a bit about cars and tuning and what kind of tuning we could do for his car.  We informed him that he would need a full tune and a BMC air filter and could achieve an average of  50-60 wheel horsepower and 60-70 foot pounds of torque.  Needless to say the customer was very excited and enthusiastic about getting his vehicle in to be tuned as quick as possible.  On BMW’s there is an adaptation period that goes along with completing a tune and uploading it into the ECU.  Most BMW tuning takes 105 miles for the tune we perform to be completely accepted by the computer.  The reason for this is the computer has safeguards to make sure it sees the same tune/information for over 100 miles to verify there isn’t an error in the computer.  After the tune the results can be felt instantly and will show a gain on the dyno sheet, but the car will only get better the more you drive it up to the 105 mile mark.  Here is the graph from our custom BMW 535xi tune.

Dyno Tune Comparison For 2008 BMW 535xi


The gains that we achieved are very impressive for this vehicle.  This tune can also be applied to the BMW 135 and the BMW 335.  The total gain is 57 horsepower and 61 Torque.  This number will only increase through the next 105 adaptation miles.  This tune costs $795 dollars and yields impressive gains. If you have any questions about this tune please contact Jesse Yorty at Jesse@smokeysdyno.com.

2000 Chevrolet Camaro SS “Revived”

50HP Gain/ 47 Ft. Lbs Torque

This 2000 Camaro SS came to us after a Trickflow heads and cam upgrade.  The car was down on power and the owner was looking for us to find the cause.  We did an initial pull on our Superflow Autodyn AWD Dyno only to see 383 RWHP.  By our calculations this is roughly 30 HP low for the upgrades done to this car.  After some initial in-depth diagnosis we found the Flowmaster muffler to be clogged.  We removed the entire exhaust system, installed our custom tune and ran the car with open headers.  The Camaro then picked up a 15 horsepower gain.  While the gain was good it was still not enough.  We then decided to check the spark plugs.  The vehicle had the original plugs in it.  We informed the customer that with his specific application he needed to run a copper core spark plug with a smaller gap.  After installing the plugs we saw an instant 12 HP gain.  Not bad for 16 dollars.  After finding the factors holding back this cars potential we then added a Fast 102 Intake Manifold and a Fast 102mm Throttle Body.  During this installation we decided to inspect the pushrod length.  The pushrod length was fine, but whoever installed the cylinder heads and Harland-Sharp roller rockers neglected to use thread seal tape on the intake rocker arm bolts.  This leads to oil being sucked into the intake which caused this vehicle to burn/use roughly 1 quart of oil a month!  The reason being on CNC machined Trickflow cylinder heads the intake ports are opened up so much more than stock that the rocker arm bolt protrudes into it.  We fixed this problem for the customer and installed the Fast 102 parts onto the vehicle as well as a customer provided Corsa Cat-Back Exhaust.  This combination of engine diagnosis and tuning added a whopping total of 50 HP and 47 Ft. Lbs of torque at the rear wheels.  In conclusion we feel that if the customer replaced his 1 5/8″ SLP Long Tube Headers with 1 7/8″ Kooks Long Tube Headers and Y-Pipe he would gain an additional 15 RWHP.  Needless to say this customer left us extremely happy and loves driving his car now.
