I went out for a drive tonight and took it to 8psi and it stopped pulling.. I was like gay.. and went to boost again and it didnt boost.. im like oh.. charge pipe popped.. so I go check the pipes.. theyre all on.. I tightened all of the pipes up and everything and did a idle rev and could feel air out the bov when vac opened it.. so I was like wtf.. must be throttle body pipe.. so I took it off and can feel air comin out of the TB pipe.. very weird stuff.. and it keeps makin this sputter when I rev.. almost like a spool down type of noise in small sputtery backfires. Pulled the plugs and theyre dark black..
