Just recieved it this afternoon. Very simple installation, but not easy... not much room in my FXDF to fit everything. Started right up, and quite honestly I cannot believe the difference in how my bike runs!

 

When I put one on the old ladys TriGlide with Big Sucker and slipons I didnt really notice any difference except when I would get on it I didnt hit the rev limiter like I did when it was set to stock rpm. Not something I do all the time but when "testing" you gotta wind it out.
