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.

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.

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!
