power for dollars

Price for power is to high because lets face it power is our main reason for purchase. So give us gas powered customers more hp or a better price value.

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.

Performed as promised

Reviewed By Christopher W (Troy, MO) Reviewed for a 2007 Hummer H2 —3/5/2015 11:00 PM

Installation wasnt as easy as stated, had to trim my "factory off road cover". But once that was done, this unit woke up my 6.0 LQ4. Had it for a while now, only bumped mpg by 1 gallon,,,, but worth it! Especially when I show other H2 drivers my readings!
