as everyone probably knows by now, i have huge boost spike(6psi of spike to be exact), today i took the joe p off and ran the hose straight from the compressor nipple to the wastegate and i got the normal 12psi of boost but with absolutly no spike at all so i would think that would mean that it is my boost controller. now my next question is, if it is my boost controller what can i possibly be bad in it causing this to happen?
