If his boost was at 9.5psi at 5000rpm and basicly held around there till redline . His belt was slipping . Either from a loose serp belt or a combination of serp belt and higher preasure between the IC and blower

 

Kevin, Did you get new numbers yet with the 550 injectors & re-tune?

 

Ya, I did go back to MacAuto for a re-tune with the 550s. We had a hell of a time with two stuck injectors, torn seal at the end of the fule pump in tank. After all this it went great, richened up AF @ hi boost. Still about the same hp #s but it sure does feel better!! Lots smoother through the whole rpm range.
