I have a new crate engine/tranny in a Wagoneer, harness done by John at Speartech. I have HP Tuners and other than look around at the tables, I have not made any changes other than set the idle up some. It is a 430HP with stock tune. My question is about a performance tune that will wake up the engine some and more important a trans tune that will crisp up the shifts. I was hoping for a tune that would be considered a standard sort of performance tune that would free up hp that GM keeps surpressed for emissions or some other reason.
LS3/6l80e crate motor needs trans tune question.

NEW!!!
I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.
