Used it to delete my duramax. Great tuner, easy to use.

Unlocked power
So far so good . Adjustable tunes on the fly and better gas mileage as long as my son isn’t driving

Super happy with the performance of this device. I can really feel the difference in my truck. Gained a little mpg's as well.... Bonus.

Great tuner
Installed this tuner on my 2009 Duramax. I have pulled with it several times and it works great. No smoke at low boost and more than enough added power for my needs.

Buy it
Best thing I’ve ever bought for my truck. No words to describe how much better the truck feels.

Wow!!!!
Made her a whole new truck!!! This is a must, delete all of the restrictions and let her breath!!! The throttle response and horsepower that the module unleashes is unreal. Will buy for every truck I’ll ever own.Read full review

H$S mini maxx
Do not buy I've only had it a few weeks and one day it works next day it dont. Already replaced hdmi cord and obd box once. For the money you pay it should work without all these problems. Nothing but trouble.Read full review

Disappointed
Easy install. I tried 3 of the factory tunes and all throw a plum of continuous black smoke from half throttle to full throttle. That doesn’t work for towing my camper can anyone help me tune this thing?Read full review
