Back to Supercharged's issue - too much power for CMC - AI it is I guess.

Maybe the combo of underdrive and y-pipe? I run the stock exhaust - factory y-pipe through a gutted cat and just dumped behind the axle. 39mm plate (of course) and was 262/309. On a motor we boiled dry at Houston Jan15.

Maybe get Sean to chime in about where he picked up his exhaust restrictors.
Can you post an image of one of your dynos? I want to see if yours falls off before the rev limit. Mine doesn't, and I suspect it's because of the aftermarket y. Kinda surprised nobody has before/after numbers to quantify the difference here. I know Ryan went back and forth, but I don't know how much of a difference it made for him. Per the google, the pulley ought to be worth 5ft/lb at the wheels or more. Mine's pretty aggressive.
