To reply to an eariler question on the PC. The PC is installed and the race tuner map is left on the bike. There are more options or areas a race tuner has over the PC. The PC builds the map with sniffers and corrects the tuners map just like it was the OEM map from the factory. We looked at the fuel page and if the PC only added or subtracted fuel with small single digits, then the tuner is close. After my build the thing had + and - numbers in the 20's and 30's for some cells. I think he said one area the PC doesn't have is fuel enrichment and a few other things for a cold motor. He also prefers to tune the timing with the tuner. I have no experience with the PC so I can't say what areas their program has for tuning. I just know NOT to change the tuner map once the PC map is built for the bike. I have a copy of the tuner map so if my ECM fails one day and buy a new one, I can put it back to the way it was. I just can't get over how smooth the motor runs now. It was never that way before, even bone stock from the factory. Will have it dynoed on April 5th.
