My two cents

Reviewed By Braden W (BELLEVUE, NE) Reviewed for a 2003 Chevy Tahoe —6/5/2013 8:43 AM

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!

I like that you can custom tune with it and do away with the soccer mom safety features

I got one for my 05 jeep wrangler unlimited. I was a little disappointed in that not all the engine options were available for my jeep because it's not a Rubicon however the settings that it does have work great! Lots of horsepower and VERY easy to use.
