my car is trying to eat itself with vacume, at idle the intake has 35psi and when you rev it up on the down rev it hits close to 70psi. i have never seen anything like this, i thought my gauge was wrong. after checking it i found that it wasn't.i am using the port on the pass side of the throttle body.the motor has a nitrous cam and t.e.a. ported 5.3 heads with ross 11.5 pistions and a ls6 intake. any idea?
