I just got my '13 CVO RG back from Doc's Performance Tuning. Doc sent my heads to T-Man Performance to have the heads flowed, larger intake and exhaust valves and pistons shaped to fit the new valves. Doc added adjustable push rods and a Cometic head gasket and installed and tuned with the TTS Master Tuner. Kept the 255 SE cams. My torque is crazy strong all the way from 2,000 through 4,750 RPM. HP is only 101 but the torque is what you feel. My compression is only 10.2:1 so I have a great deal of reliability with the engine. I attached my dyno sheet for your review. I see all these guys installing 259 SE cams or the TMan 666 cams. Great for high end torque but when yo review their dyno sheets they sacrifice low end torque and usually end up with less than 95 foot pounds until they get to 3,000 RPM. I don't know about how you ride but everyone I've ever seen rides from 2,000 - 4,000 unless they race their bike. Since you are pulling a camper I would think you want the pulling power from off the line to 4,500.
