Steve, that AUAH is the stock original chip. Marc H will be able to get you the upgraded GM chip which I believe is AYBK3 and he adds his goodies to it as well. Go to his site which is "ZR1 specialist" and check out the new chip advantages over the stock one. I have the upgraded chip from Marc and it works great.
