One had stock turbos and put down 400 whp. Imo the trany felt soft between shifts at wot but shifted firm driving around. It was not damaged, just not as crisp as i expected. Second one had upgraded turbos and a built shortblock, we could not tune it any higher hp due to tranny slipage at 18 psi. Customer switched to sz trans and it held plenty of power with zero slipage. Just stating facts, not looking to start a war. When you you claim 10 sec z's wi these tranny's i am not sure they will last at that power level. I understand everying wears out but " last tranny yiu will buy " is a very bold statement indeed.wish it was true but from what i have seen, not really. Harry
