i have a2008 rocker.Im going to put set of big radius 2-2 and a roland sands air cleaner having trouble deciding on what to use on the fuel injection any feed back will be greatly appreciated

 

I have the Big Radius pipes on my 09 Rocker with Thunder Monster QQ baffles and Screamin Eagle air cleaner. I used the Vance and Hines fuel pack on my bike and it runs good.

 

I also have a fuelpak on my 09 fxcwc for my martin bros pipes. Works great, and have had great customer and technical support from v&h. i had to install it twice, and found the second time with the fender removed, it was alot easier to get everything in place and wires routed. just a heads up. good luck.

 

I recommend the Power Commander because it adjusts the fuel for the complete range of throttle position, whereas the FP only is in the loop for >36% throttle. For less than 36%, the stock map is in force. There is a company that makes a special stainless steel box for easy mounting on the Rocker for about $75. The tech support guys at PC has his contact info. If you go with the PC, FuelMoto has the best deal, including pre-loading your map for you, and extending the warranty to 2 years and lifetime map support.
