Hi im very confused, i have a boosting problem and i have recently cleaned the boost solenoid and im now hitting 15 psi and holding 11, is this right? my car is a 1997 wrx import with full decat and a HKS induction. I have checked all the pipes, prior to cleaning i was hitting 17, 20, 15 and on average holding 15 psi, why would this have dropped?

Cheers
