Also to expound on this, don't expect an mpg increase with any forced induction. It works on new cars that are built around it, and efficiency is the game, but slapping something on a 4.0 will, at best, result in the same mpg, unless you want to start getting into lean burn tuning which would only be out of boost and is irrelevant.
Which brings me to the tuning, if I'm not mistaken the Banks comes with preset tunes on some sort of proprietary device. If you want to actually adjust any individual parameters you'll need to get an HPTuner and the credits for your VIN. I could be wrong though, I don't know the capabilities of the Banks tuner. But I do have a raw copy of a Banks tune pulled from the PCM using... an HPTuner lol
This is good. Exactly what I was looking for. Thanks
