    Its pretty unlikely that an aftermarket pcm is causing your problems. The pcm really has minimal effect on takeoff other than commanded line pressure but that is pretty much a fixed setting and not something that pcm tuners will or can change. You could always try another pcm if in doubt but I doubt it will cure your problems, and if for some reason it does it will only be short term as it learns to your trans and pressures are adapted to it.
