I installed a V&H 2 into 1 Propipe, Doherty Machine AC, and a PCIII on my 07 Fatboy. The PCIII came pre-loaded with a map that was supposed to be close for my set-up. It ran very good, but seemed a tad rich. Gas mileage was not so hot. So last month I was at Rossmiers HD in Daytona for Biketoberfest, and decided to take a chance on Speeds Performance. I spent a good bit of time with Wayne (he's the brains of the operation) and his sons. He did a great job with my tune. Bike has more throttle response and runs smoother. I feel it was money well spent. Not sure I would let them rip in to my engine, but for a dynotune they were great. $300 clams seemed to be in the ballpark for this service.
