Overboosting
I finally brock in my rebuild and today I was driving on the highway and gave it floored the pedal a little and the boost gauge read all the way to about 15psi So i really freaked out because I hope I didn't want to mess up my motor. I have rtek 1.8, corksport 80mm downpipe, stock turbo, turbo xs hpbc. I checked to see if the boost controller was on the lowest setting and it wasn't so I adjusted it and drove the car again. Still no luck the boost just keeps on rising and i'm not even at 6,500 rpm. I can't even WOT or the boost would really go up!!! Why is my boost so High, it seems like the boost controller isn't working.

My boost gauge is connected to a UIM nipple. And the vacuum lines connected to the WG are fine. Nope the WG is not ported, maybe I should check to see if WG is bad.

So I ported the wastegate and still very high boost at 5,000 rpm im hitting 13+psi. It seems like after porting its gotten better but man this sucks. Maybe a high flow cat would help. Why would my boost still be so high?
