I had my dealer install the SE Stage II on my 2011 Road King to go from 96ci to 103ci. It has the SE air filter, V&H Power Duals, V&H Monster Rounds mufflers, and a V&H Fuel Pak. The bike seems to idle a little rough but runs good otherwise. Is the Fuel Pak good enough or should I look for something that does more tuning?

 

The Fuel Pak does a decent job at modifying the fuel circuits and many have them & are happy. The downside to the FP is that it can not be custom tuned like when on a dyno run. V&H does not give out what the FP numbers do or what areas they control so you're limited to the settings they provide. To get a properly tuned EFI set-up you will need a different EFI tuner that allows custom programming.
