Boost leak help.

Young_Man · 08-30-2016, 07:42 AM

I had a log reviewed recently and it was brought to my attention that I had a major boost leak. All vacuum lines have been replaced. I also checked the charge pipe and intercooler connections and couldn't find anything. Would the wastegate solenoids being bad cause what appears to be a major boost leak? "wgdc is already at 70 % for really low boost targets" is what my tuner told me. Any input would be greatly appreciated.

I had a boost leak by the TMAP sensor. The o-ring was pinched.
