OK.. As usual I had to come over the buick site to get my answer. Seems no one on the Ford sites can answer this or maybe I'm just to impatient....Here the scoop.
I recently switched my exhaust.
Old Exhaust= 3" down pipe to a 2.25" y to a 2.5" high flow H pipe to a 3" duel catback system. The car was making 11# of boost.
New Exhaust=3" down pipe to a 3" single high flow cat to the same 3" duel catback system. The car now making 9# of boost.
Did I create more back pressure and this why I'm seeing a loss in boost. If so what can be done to correct this problem. I'm running a T63e with deltagate Mark II wastegate.
Thanks in adavance for any and all replies.
