Purchased a 09 Ultra with complete engine Screaming Eagel kit, duals, on a 96 motor. She lags on take off unless you build her up, she also sputters at 60 mph going up hard, runs rich. running 93 octane. Harley shop says its the cam, she wants to be run hard at high rpms, and it cant be worked out through they tuner. Didnt purchase a Ultra to dog the crap out of her. She definitley run amazing when you do kick her. Tech says " I bet she is hard to hold on to at 120mph.
What can I do, is this the way she is supposed to perform?

 

Maybe try re-posting this in the engine section. Be prepared to give more specifics on things like which cams you are running, exhaust, etc.

 

Definitely sounds like one of those proverbial Catch-22s, man...
