Just bought a Hypertech Max Energy programmer
Yea you can adjust for speedo and gear changes!
Well one things for sure I don't regret my purchase by a long shot! I'm extremely impressed in the power gain! The throttle response is dead on now with hardly any lag. The shifting has firmed up a lot too! The installation was simple and so far I don't have any complaints with this programmer other than the fact I can't keep my foot out of the throttle now!

My best mpg without the programmer was 17.4 mpg with a 50/50 city and highway driving and that was driving as light footed as possible!
Correct me if i'm wrong but aren't custom tunes designed for only one truck? That's one reason why i'm not getting custom tunes is cause I wanna be able to sell the programmer when I decide to sell my truck.
The Xcal does comes with canned tunes as well as a custom tune specific to your calibration code, mods, and so on.....mine has an 87 and 91 octane custom tune specific to what i have done to my truck.
