After more than a year and several alleged dyno tunes by HD dealers I got my bike to run right. I always assumed my Vance & Hines Big Radius pipes were mostly to blame for the poor performance. I was wrong. I started looking for different MAPS for the 254e cams and came across one for the following equipment: 254e cams, Heavy Breather, 10.5 comp, 110" heads and race exhaust. The base MAP the HD dealers used for my dyno was for: 254e cams, FT pistons, SE Breather, and race exhaust. I loaded the new MAP to my Road Glide and damn, it was like a different bike. Finally. Last night I started adjusting the decel enleanment to get rid of some popping and that is almost all completely gone now. My bike now runs like it should and I couldn't be happier. I may not buy that Dragos 2-1 pipe after all.
All that being said I have a not-so-good opinion of HD dyno tuners. 2 different dealers attempted to tune my bike. I can look at the MAPs and see what they did and what they didn't do. Obviously neither even bothered to adjust the decel enleanment cells and as far as I'm concerned they did not use the correct base MAP for dyno-ing. What the heLL did I pay for and what the heLL are these people doing? My bike runs good now and I'm happy, happy, happy.
