3rd dyno run

This is after installing a Kerker 4-1 exhaust. I gained a whole 1hp by installing the exhaust... but there's still something wrong. Video of this run can be found here: http://vids.myspace.com/index.cfm?fuseaction=vids.individual&VideoID=35733771 During a rejet, I discovered a torn slide diaphragm. 4th dyno run coming soon
