just came from doing a track day and got black flagged for noisey car (107db) but the noise was when on high boost in 2nd gear coming out of corners. also had a dyno other day and it made it but just thought it was from the pipe they put in exhaust and dyno says that power drops rapidly after 5000rpm. no engine lights on. seems to be a boost leak at high rpm. any ideas or thoughts?
oh and its a 2001 c70 t5 me7
