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”

–Roy, USA



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. Im so excited to see final hp & ft/lb gains when it fully registers the engine. 1000000% Best purchase for this vehicle..”

–Ted, USA



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
