I have a manual jza70, however a mate of mine (SYC01J), has had a boosted jza70 auto for a couple of years.
I assure you when this car was auto ( now converted) it had no probs frying the tyres off the line. I think with good tyres it would launch at 2800 with just a hint of wheelspin.
But certainly no problem about not enough wheelspin or boost production on a power launch, quite the opposite.
All this with 295/30/18 pirelli p-zero's on the rear !!!
