At the heart of the Stealth Tuner is many long hours of precision tuning combined with thousands of miles of real world testing. We combine the use of fuel injection pulse width and injection timing to create the ultimate horsepower and torque curves. The precision tuned timing maps are one of the reasons our tuner has the lowest exhaust temperatures on the market. Perhaps the best part of the Stealth Tuner is the mileage gain that you will see. We all know that a more efficient engine will gain fuel economy and we know exactly where the stock parameters are lacking. Depending on your driving style, you can expect to see a 1-4 mpg increase! 
The Quadzilla Stealth Tuner is packed full of power and features for your 2007-2008 LMM Duramax. Among these features are power increases up to 110hp and 250ft lbs of torque. Also included in this awesome tuner are the ability to modify your speedometer to compensate for larger tires*, remove your top speed limiter*, retrain your transmission, and read and erase engine and transmission fault codes. All tuners also have the ability to use these user-defined categories without installing an engine tune. 
Combine all of this with the best reliability, and you can't go wrong. We offer a 1 yr warranty on the tuner and a LIFETIME warranty on the software! No one else will match this. Quadzilla also offers free updates and revision to the original owner FOREVER. **This works on ALL 07 - 10 GM Duramax LMM 2500HD/3500 Pickup Trucks - Please be aware, on 09-10 trucks, you will need to keep the EGT sensors plugged in to the frame connections to make the programmer work w/o a Check Engine Light**
