The Quadzilla Stealth Tuner is the ultimate handheld programmer for the Duramax. While being extremely well-know for being the most powerful handheld tuner ever produced, it also offers many other features that are important to you.

  • 5 SETTINGS--ECONOMY-50HP-70HP-90HP-110HP  THESE ARE REAR WHEEL NUMBERS
  • TOP SPEED ADJUSTMENT
  • TIRE SIZE ADJUSTMENT
  • GEAR RATIO ADJUSTMENT
  • READ AND ERASE DTC's
  • USB UPDATABLE
  • 2-4 MPG GAIN IN FUEL MILEAGE

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 2-4 mpg increase!

The Quadzilla Stealth Tuner is packed full of power and features for your LMM Duramax. Among these features are power increases up to 110hp. Also included in this awesome tuner are the ability to modify gear ratio, remove your top speed limiter, 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 in 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.

UPDATE: LMM No DPF download available here.

I've had Quadzilla on all 5 of my Duramax's and have never had any issues with them. The customer support at Quad is awesome. Justin there is very helpful and knows his stuff. I will only buy these tuners for my trucks. There so easy to use and if you have any troubles you can actually talk to the guys at Quad and they can help you. There number 1 in my book.

Fot the LMM this has so much more usable power than six gun or edge juice. The egt's are lower and it never throws any codes. Get the edge insight and you have the perfect package!

Works great plus you can upgrade for free at quadzillapower.com. I never tried the 135hp nor 165hp. Afraid the transmission won't hold together. I'm happy with 110hp but drive it on 70hp.
