yeah i have a cobb uppipe and and a cobb tbe. i was really careful when installing them and used all new gaskets. what are the chances you think i have a leak? it sounds tight, ie no raspy tick tick tick noise. i was under the impression that because of my 3" exaust that it reduced the backpressure which helped close the wastegate, which now isnt getting as much pressure as before and is why it flutters under partial boost. is this wrong? thanks for any help
