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!

Awsome tune for everyone

Reviewed By Walter M (Queensbury, NY) Reviewed for a 2006 Hummer H2 —1/24/2009 8:13 PM

This only took 5 minutes to do and I was able tune for 87 octane gas. I picked up 2 mile per gallon around town. The hummer is about as aerodynamic as a brick so I really did not see any increase on the highway. A nicer feeling off the line. It make you fell equal to the other vehicles that weigh 3 times less than you do. If you own any hummer or chevy with a LQ9 engine this tune is a must!!
