I have a 2004 FXSTDI, I am running S/E 10.5 compression pistons, with screamin eagle CNC heads, Lienwebber cam (560 lift), 50mm S/E throttle body, arlen ness "big Sucker" A/F, and a twin tec dual system WEGO III system. I am considering the Supertrapp 2:1 Super megs. Would like to know if this is a good choice, If so how many disc should I start with, and If not a good Choice, please direct me. Have'nt seen much on Fuel Injection systems.

The 2:1 SuperTrapp SuperMeg will provide the most power gains. The system comes with 20 discs, I would start tuning with 18-20 and have an extra 6 pack of discs or an "open" end-cap available for further tuning.
