Ran Innovative tunes for a year and a half on 2 different trucks and loved them. Ran like a stripped ass Ape.
Same here, I burned up the factory limited slip-clutch packs w/ in the first few weeks of getting the truck tuned..:doh: but it was fun.
Overall I've had great service from IDP. The Ext-X is a perfect daily if you want no smoke at any cost, however the mileage isn't great for my vehicle.
I went back to the Xt-Street and I'm just careful w/ the pedal, and it gets me upwards of 18 mpg w/ a best of 24 mpg by hand. The trans shifting was solid and firm, and w/ the trac-bars things are smooth as silk.
IDP always returns my emails and modifies tunes to my liking when I want to try something new.
