Yeah, I've heard that. I have LT1-Edit for my Fleetwood and LOVE the things it lets me do to my PCM. My wife's Denali has ALWAYS driven me nuts with the piss-poor trans calibration from the factory. I've tried several times to get the dealer to do something about it but they just say it's operating to proper factory specs etc.
