After my supercharger install I want to try to fix some of the flare I'm getting in my shifts, especially accelerating onto the highway. I got the Transgo 340-HD2 reprogramming kit like a few others have. I haven't installed yet, but will drill it for "truck". The one complaint I've seen with that kit is a hard 1-2 shift. That has me wondering if I can not enlarge the 1-2 port to minimize that. Either that or drill it out less than what they specify with the "truck" settings. Anyone know if that will cause problems?
