I'm running a JDM V7 topmount with alky at 22psi peak boost. I've been hearing what sounds like a boost leak for 3-4 months now. The noise was there before my alky kit and tune. The car is still making good power and holding a fair amount of boost but air seems to be leaking out of the motor somewhere according to my tuner. He had a hard time keeping the A/F flat while tuning. I've checked all the usual subjects, replaced gaskets etc.
I'm wondering if the IC is leaking and if anyone else has had a similar problem.
