hey there,
This is more of a question than an answer, but here goes. Doesn't the boost depend on how much you push the throttle in? Also doesn't it depend on how well you are driving upto that point? I was also wondering, if your boost goes down 3 psi that is a lot more than a little leak, I mean there is a big difference between 15 and 18 psi...Anyways those are my thoughts on the subject. peace,
hippy
