Awesome piece of equipment but not for the novice.

Awesome piece of equipment but not for the novice. This tuner has the ability to fine tune almost every aspect of your vehicle. Without knowledge of the items it can tune for you I suggest: either use the installed program or download a proven program, or change it 1 increment at a time and thoroughly test the tune before adjusting again, just to avoid costly damage no covered by any warranty. Monitor the settings with the unit and create a log file and keep it for reference. With oversize tires, cold air induction, and cat back exhaust and predator i am able to improve my gas mileage by over 4.4 mpg with in town driving. And performance thru the roof :-)) AUTOANYTHING was GREAT TOO!

Good but pricey!

Reviewed By Aric M (Hanna city, IL) Reviewed for a 2011 Chevy Silverado —6/2/2015 3:30 PM

This was pretty good programmer i could really tell the difference in acceleration and power. I have not had it long so still unsure of mpg gains but it seems like a tank of gas goes further than before. Was a bit expensive but at 20% off had to try it!
