Hi guys i have a 94 R2 and today im losing boost. i drove the car 2 days straight to school. When i was driving home i heard a weird air sound it like something constantly kept shooting out air. It would only happen from 2000RPM and up. I opened the hood and checked on all the visible vacuum lines and they alll looked fine. But the car will only boost up to 5-7 Psi. what do you guys think this is? please help Also my mods are a K&N drop in filter Greddy downpipe and Catback, Petit oil catch tank

 

You need to take apart the intake piping starting at the turbo y-pipe and going in the direction of the intercooler and throttle elbow. Once you have the rubber coupling removed (you won't see this with it installed), inspect it for small tears or holes. Replace what is damaged.

Do not overtighten the metal clamps.
