I got the se hi flow kit, se race mufflers, and stage 1 chip dyno max power=83.55 at 5000rpm max torque=97.46at 3900rpm was a 87deegree day just came in from a 400 mile trip ,I guess this sound normal. Wanting a little more torque & power I ask the dealer were I got the serk 103 from if it would be ok to go to the power commander and the reinhart exhaust that I read that some of you have a fitting issue with the Reinhart. The HD dealer said that we would have a problem with the ext. waranty if I should need it, is this so? He thinks we could pull it off if we go with the race tuner from harley.Has any body been down this road. Is it worth the 1000.00 bucks for 5 more lbs of torqur. This bike starts good, never spark knox, get 40 mpg on the avrage, used 1quart of Syn 3 in the motor on a 4500 mile trip. Also use syn3 in the primary, and in the tranny with a clean drain plug on the tranny drain plug. The primary drain was pretty dirty. When it is show time I tell the wife to hang on tight and we pop a wheelie with the King, she gets a kick out of the guys on the side line laughing and smilling with a thumbs up wanting to see that again. Some fatherly advice would be very welcomed. Ride on Ride safe don
