Wow, installed the downpipe and flashed Stage 2. Took it to a highway onramp letting the computer learn a little before I punched it. Holy Crap!!
Didn't take 20 minutes and I was hitting target boost. Stage 1 is a smooth powerband. Stage 2 is just a rush of power right when you need it. This car can power out of corners like my RS does, so much more fun.
