Being a turbo, we'd be looking at pressure rather than vacuum. On the gauge in my LPT I am seeing peak sustained boost as high as 18psi. This may be a psi or two higher than before, but to be honest the car is accelerating so wildly at this point that it's hard to take my eye off the road to study the gauge. ;-)

I have my gtech back and can see if I can beat my 0-60 in 6.4 number. But if I do I'm not sure that that would prove anything either. There are so many things that effect this that once you have the gtech you realize it is BS to a certain extent - all aspects of weather, fuel quality, and launch can affect 0-60 pretty dramatically from what I've seen. Never mind number of passengers and the AC

But qualitatively, it feels pretty good to me.
