Default UPDATE on my transmission clunking/ power cut issue.. Stock TCU= no more problem
switched the giac tcu w/ stock tcu, and no more problems
shifting while in full boost is seemless w/ no clunking/ slipping feeling
maybe the communication error was b/t the apr ecu and giac tcu, but i ran it for almost a year just fine..
hope it stays fine the way it did today
if the problem comes back, i will know its a problem w/ the apr ecu
thanks guys for your help

Glad to hear it was not actually the trans slipping.

So when you do the APR trial, the files are stuck on your ECU? I cant load GIAC cuz of that!!!
