I was planning to firm the shifting and potentially change a few parameters, I am not sure how this will effect the tune if I have my custom tune done before adjusting. Probably better for me to wait until the TCM support is out and can be adjusted if needed. If I am wrong please correct me though. Thanks.

uuhhhh... tcm support is out man, you can adjust that stuff yourself now... if you're particular tcm/tranny calibration is not supported and you can not, then you need to post up your tcm original backup tune file here so that they can add support for it in a new trinity update...

I've posted the info on here. I tried the update that was provided by mikel but it doesnt work with my truck. In addition to the adjustments, I also intend to change out the tires to larger ones and want to be able to compensate for that as well.

k.. then keep on top of it, let him know it doesn't work... keep posting to your other thread for it to keep reminding them, so they see it... they'll get it...

Sweet! Got it downloaded & installed. Seems to have worked. I am about to hop in the truck to go run an errand & see how the TCM & PCM tunes work on the road. Thanks again for all the help & the update!
