[QUOTE="1NA RUN, post: 12808063, member: 145151"] Strapped the vert on the dyno today after some minor upgrades and was baffled because it lost power. After about 2 hours of trying different things, we decided to disconnect the exhaust behind the down pipe. Turns out my single 4" muffler was creating too much back pressure. It instantly picked up 102rwhp from the previous pull. We were extremely surprised at the result. Next pull went up 2 more pounds and ended up with a comfortable 929rwhp at only 20.36lbs of boost. This is with a precision 88mm. Obviously has more in it, but that will do for now. Problem is, now I only have a couple of days to figure out how to add mufflers for NMRA true street without the excessive back pressure. Any suggestions would help.
