I have a retraction to make. The guy who printed out my last set of dyno's made an adjustment that shouldn't have been there so they were 3 hp higher than the standard that I have used in the past. Just another example of dyno's not matching up.
I switched the 80mm to a pro-m 75mm and didn't gain a dam thing. After making all of the fuel mixture changes I could almost line the charts up. There has to be a restriction limiting the air and the precats come to mind. Guess what is coming next....
