My experience was much different. I went to Cycle Rama who did head work, cams, and dyno with my Race Tuner. Sure enough my Ultra had awesome power, but only on full throttle to red line. It wouldn't go 40 mph to save my life - just bucked and surged. Long story, but Wes couldn't (and wouldn't) fix it. I rode the bike directly to the HD dealership and traded it for a year older Street Glide CVO with less miles. I then took it to Doc's to wake it up. He installed T-man heads, exhaust, no cams, TTS tuner and dyno'd it at 109 HP 125 TQ. Runs very strong but it also runs slow and tours like a kitten. Mine is a 110 Screaming Eagle 2010 Street Glide CVO. My experience with Doc was great.
