Anybody have any problems with there tranny running the custom tunes or the ones that come with it. Does the stock automatic seem to hold up good.

All depends on who's tunes..Cale at BTS IMO no tuner knows more about these trans than him since they build them.

There is a learning process that these transmissions have to go through you u upload a new tune. So it might act wierd a little in the begin, drive it around at different speeds in town, and left it adjusts itself, then do some highway driving but dont mash down on it right off the bat.
