Well I did the SE air cleaner as well as the ECM Stage 1 download. I still have a slight stumble at 1800 rpm to 2200 rpm on decel. Is there anything that will completely eliminate that? Also I did not do pipes as of yet. My dealer said he will have to do the re flash again once the pipes are installed. Is that true?

 

When you are decellerating and really let off the throttle, the computer will go lean due to emissions, mine has a tendency to POP alot, not sure if this is what you're referring to!![&:]

Relfash with pipes? I guess it depends on if your going with just mufflers or a whole new complete setup. I guess you could put them on first and see how she runs, but for optimal performance, a retune is probably the way to go. Of course dyno time costs money.[&o]

Tell your dealer he full of it, he's trying to lighten your wallet. The same reflash is used for both. Go with the TFI and do it yourself. Look in this forum for info https://www.hdforums.com/forumid_247/tt.htm

And you can get it here.. TFI

 

Thanks for the help. I used a TFI on my last bike and felt it was well worth it. I will go that way again.

 

OR a pciir usb if you plan on any future mods, or a SERT. Which one will depend on the tuner in your area
