TunerPro .XDF for Throttle Mapping Hi all,
Finally got my trans tuned in with TunerPro and got it shifting as close to right with larger tires, night and day difference between before and now. Currently looking to get my throttle mapping as close to 1:1 as possible to fix some touchiness and dead spot issues. Anyone know of an XDF for the 12587603 OS?

I think the mapping you're looking for is in the TAC, not the PCM. It would be great to be able to tune that but I don't think anyone (outside of GM of course) has a way to do it.

Ah, I thought it was possible with HPTuners but that may have just been bad memory lol. Thanks
