No, it's not hesitation or LAG I'm talking about. I don't have much lag at all after my Dinan upgrade. It's much more responsive on a straight-away with the CAI and the new exhausts. The problem I was talking about is a violent, "jerky" transmission misfire when the steering is turned more than say 20 degrees. As I gun the gas during a turning merge, the car jerks to a stop, then jerks forward, then jerks to a stop again.

Dinan does not have tranny software for the 04 to 06 4.4s. So I have the stage 3 engine software, but not the tranny software. I have no idea if that's part of the problem.
