Quadzilla Stealth 2 Tuner for 06-07 Duramax |
|
|
Quadzilla has finally released the Stealth Tuner for the 06-07 Chevy GMC Duramax engine! They have really gotten something out of this one, up to 135HP and 300 ft/lbs of torque! You can also reset the speedometer for tire size and gear ratio. It will also remove the top end speed limiter and reset the transmission. Quadzilla is telling us that this programmer will add 2-4 more mpg. This is critical with the economy losses we are seeing on the new Ultra Low Sulphur Diesel Fuel.
As they normally do, Quadzilla has also put in the features to allow this downloader to read and erase diagnostic codes. A first, however, is that it comes with a USB port, allowing you to update new software revisions over the internet! The tuner will work on 06 and 07 Chevrolet or GMC Duramax engines with either the LLY or LBZ designation. If you have lifted your truck, this really helps as the Stealth 2 tuner will give you back some of the lost horsepower and reset your speedometer for the larger tires. As an added bonus, this unit also works on the GMC 4500 series trucks, the Top Kick!
