Case Studies

Real testimonials from our customers:



Vehicle: 2005 Saab 9-3 Aero 2.0L

“I would go on file to say its one of the best preprogrammed chips i have used. I would recommend this to any saab aero or saab user. There is so much torque steer. It wants to take off. Do you have a chip to help keep the car on the ground”

Vehicle: 2013 Nissan Altima

“Put it on my 2013 3.5 sv Altima just to see what happens. it said about 2 weeks you’ll notice power increase. In like 3 days im breaking traction from a deadstop at every traffic light. The Torque increase is immense, and I still haven’t even topped out the car yet. The throttle response has become butter, and gear change is seamless, even while CVT.

Vehicle: 2006 Buick Rainier 5.3L V8

Great Tuner! I immediately noticed better throttle response and that third to overdrive gear lag went away! It took about 200 miles before it completely tuned. 

Noticeable gains include:

Throttle response (immediate upon installing)
Transmission shifting improvement (removed that lag when A/C on between third and overdrive)
Highway passing 55 to 75… Huge gains in 55 to 75mph and very smooth and noticeable power gains
All around smoother idle
2+ mpg increase in city and highway 

Cons: For the first 150 miles gas mileage actually reduced, but then slowly became better. Seriously I thought this was all bull but it truly works




Vehicle: 2007 Ford Sport trac 4.6, 2012 Infinity G37X, and 2006 Infinity FX35

“All 3 have improved performance and 2 to 3 mpg in town and 3 to 5 mpg on the highway.
Thank you Sawyer Tuning

Vehicle: 2011 BMW 328i

Vehicle: 1999 Lincoln Towncar

I have been using Sawyer Tuning OBD plug in performance tuners since 2011 on my former 1997 to late model GMC/Chevy full size trucks, late model Camaros, and especially now on my 1999 Lincoln Towncar. There are more cars on the road now, they move faster, and sometimes you really need extra horsepower. I have had zero problems with the ST tuners, either mechanically or with warranties.
They are relatively cheap, easy to use, and don’t seem to lower MPG at all in normal driving. If your foot behaves you can get better MPG than stock. And most importantly, when you really need the extra HP your vehicle has, it now becomes available to you. Enjoy!




Vehicle: 2016 Dodge Challenger

“I recently purchased one of your Sawyer Tuning Stage 3 (ST8PRO) Chip module for my 2016 Dodge Challenger and noticed changes immediately. By the 3rd day of using the difference was undeniable, I was getting better throttle response and it was switching gears very smoothly (I have an automatic transmission). As far as gas mileage I saw an improvement of 1.5 miles more per gallon. I want from 17.2 miles to 18.7 miles per gallon (average seen in two weeks ) even though my Challenger has one of those 5.7L Hemi engines that are very thirsty for gas . Thank you for the great product.




Vehicle: 2017 Hyundai Sonata Sport

“Truly impressive the change of my sonata 2017 sport 2.0T. up to 19.5 Psi without problems with the st9pro. The best upgrade for the price and easy installation. Only change Evo X spark plugs.




Vehicle: 2017 Dodge Durango R/T

“Installation was a breeze. Of course I had to put the Maxx Boost at max to start. The response was incredible. After two days of feeling like I was at the drag strip I put it into the middle position. After two weeks of driving I have increased my MPG 1.5 And that is just going back and forth to work in stop and go conditions. I have not been able to go on a long trip on the highway to see what my increase in MPG would be. Over all your product performs better than I expected. Boosting your performance and increasing the MPG is amazing. I will spread the word about your products to my family and friends. And to those who I leave in my dust. Once I am able to take a long trip on the highway I will give you an update. Enjoying the ride. Thank you.



Vehicle: 2012 Mazda 3

“…your chip is amazing it completely woke my car up!”



Vehicle: 2007 Porsche Cayman, 2013 Porsche Boxster

The new ST10 modules with blue tooth on my 2007 cayman and 2013 boxster work amazing. Its amazing to see 8 horse power gain using a high performance air filters, using the ST10 DashCommand app. Obviously I don’t know how much horse power increase I got with your chip because I could not see horse power with the ST8. But I felt it when I installed it. No more guessing now we can see gains or failures every time we add components with the ST10. You can squeeze so much more power and speed from a Porsche with electronics. I was shocked to see 0-60 in 4.83 seconds after installing the ST10 and high performance air filter. The best I could get before was 5.4″



Vehicle: 2012 Honda Accord

Good morning guys!!!! Just wanted to say thank you so much. Got the chip, I installed it and yes livened the car up a little. So happy, I didn’t want anything crazy just a little boost. Your chip did just that! I’m definitely considering getting the Maxx boost as well! One thing for sure I believe in your product. Thanks again and God bless you guys!!!!”

The Maxx Boost Throttle Enhancement Controller Booster arrived quickly and installation was a breeze. The improvement in the throttle response is absolutely amazing! This is the way my 3.5 Ecoboost should have come from the factory. Thanks Sawyer Tuning!
