Should be a decent combo, better pipes, filter and a tuner for the efi, thing is you should find a good powercommander tuning center in your area to get the optimum power and mileage out of the PC unit.

Downloaded maps are rarely spot on. It may run good with a downloaded map but with a dyno tune it should run great.

I would like to know if the power commander and the Race Tuner are similar? What are the differences. I've been leening towards the Race Tuner but don't really know what that would give me over the the Commander.

I've got an 05 Road King Classic. No pipes and such yet but planning it out.

IMHO the main advantage the Powercommander USB has over the Race Tuner is knowledge of the tuner, more people know the Powercommander at this point.

Both work well, the Race tuner is a very effective tool, and like any tool it's only as effective as the talent that is working the tool.

You would have to find a good dyno tuning center that was well versed in the Race Tuner, otherwise a great tuner with a PC USB will be able to out tune a novice or newbee with a Race Tuner.

Again check around to see whos going to do the tuning.

Hey Man, I Also Have 04 Low Rider (carb.) With Ness Air Cleaner, Screaming Eagle Ii Slip On's, Have Been Thing About Putting Big Radius Pipes On. I Think They Will Look Cool On Low Rider, Let Me Know What You Think About Them When You Put Them On. I Hope They Are Louder Than The Screaming Eagles. Only Reason I Haven't Put Them On Yet Is I Thinking About Selling My Bike And Buying A Road King Custom. We Ride Two Up About 95% Of The Time And I Think The Rk Will Be More Comfortable. Good Luck With The Big Radius.
