Damn 370whp stock!? Very sweet. Sounds like you got one of the special production ones! I think 370whp is the highest stock # I've heard of.
Do you go to ICS or any other spots in NJ? Trying to find a solid local place but would also prefer that they will tap into boost. The shop I went to wasn't very good. Messed up boost one day and torque the other day! I've seen dynos without boost but no torque is something else...
