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!!

F5 Tuner

Reviewed By anthony l (MARTINEZ, CA) Reviewed for a 2007 Hummer H2 —2/2/2017 11:27 AM

I like how much faster the F5 is compared to the F4 . It has better graphics than the F4 and is just a good product overall and it made my truck a lot better to drive with more power and better shifts. I have a cold air intake , cat back exhaust which makes this tuner work even better.
