Installed the pipe on weekend, took about 4hrs, mostly just spraying the rusted bolts with rp7 and waiting around for it to work its magic. A couple of questions though, did anyone else notice that if you give it some it seems to over boost? on the drive to work this morning i put the foot down about half way to work (gives it about a 10min warm up) then a soon as the auto kicked back the turbo spool was a hell of alot louder than before and boost shot up to just below the 1+ line (didn't hear anything rattle down the exhaust pipe though, thank god), normal? should i be concerned?
