Super easy to install and easy step by step instructions for download. The premium program gave me instant pep and power. I would definitely recommend this.

Currently using the regular gas tune running 89 octane. Noticed more power than running stock with 89 octane. Moving acceleration increased quite a bit but I haven't noticed anything off the line but my truck was already peppy in 1st w/3.73 gears. Highway above 55mph i have noticed roughly 5mpg better mileage and city driving 45mph and under its about the same or worse mpg probably because its kicking in more fuel. Currently watching intake temp vs outside to see if a CAI is colder!

Wanted something to give my tahoe a little extra horsepower. Already installed k&n cold air induction and flowmasters. I did notice a slight horsepower gain with the jet performance module. It seems to respond better then before.
