hit up the dyno the other night, and the track the following day. Numbers were so so. Will post up after LSX. Seems once i finished up the exhaust to a full 3" i lost some backpressure and boost dropped. Went from 11psi to 9midrange bleeding off to 7psi. Blower isn't keeping up with the motor now. Looks like it needs to spin more. To bad I dont have enuf time to get that done prior to lsx.
