Cornbread, for what I have on my Road King , as far as upgrades, it is the most cost effective thing I have done. My '11 RK is decatted, RC Components slip ons, V&H Vo2 Stage 1 with external breathers and TTI's from DK Custom, which were needed after decat to bring back the low end torque. I have run the original flash tune for about 3000 miles. The Fp3 has been flawless. My MPG stayed the same and maybe average 1 mpg better the before tune. I have not done the auto tune yet. I don't want to mess up the performance or fuel mileage. The only issue I have is a momentary backfire on upshift from 3rd to 4th gear. I believe this is rider produced because I don't always fully close the throttle when shifting. Self inflicted issue. I will do the auto tune someday, but not A PRIORITY. Bottom line: good product, 5 stars with or with out cat. Decel pop 100% gone, throttle response quicker, low speed surge gone, 6th gear usable earlier, pulls better all gears.

 

Thank you for sharing.Ive been on the fence about this tuner.Sound perfect for a stage one.

 

Idaho, the Fp3 will tune well with your combination. I like the sound of the Crusher Mufflers. Another benefit of the Fp3 is the ability to retune in munutes if you make changes. I took off my RCX mufflers and installed a pair of 2015 Ultra stock mufflers. These sound great with a no cat header, and quieter. Was able to reflash in about 20 minutes, incl removing saddle bag and side cover. A good tool for stage 1 and now upgraded for mild cams.

 

I need to really get one.I do like the versatility of it.I do have a couple sets of pipes.I was quoted $275.00 on another forum.

 

$299.00 when you ad it to the cart.Great price.
