It's all good, I need to write an update on just installing a new supercharger! For your situation, first question how long have you had it? 4-5 Psi seems really low to me. Sounds like a boost leak or a really worn out supercharger. Is it the C38-91 or? With my new supercharger i gained 0.5-1 PSI over the entire rev range So it could be just time for a new unit.
