Recently i have not been able to get into boost much due to slipping clutch but that was fixed today by buschur now i have a exedy twin disc hd. however on way back my car won't really get above 21 psi and it sounds funny almost a secondary higher pitch intake or "sucking" noise and starts around 17 psi. i am thinking some sort of leak etc but got a cel with it as well any ideas? btw buschur great job on clutch job even cleaned up engine bay some made it look neater
