08 Dyna EFI
I recently put Rush pipes w/ 1-3/4" baffles and am looking to upgrade the air filter to a stage I. Is there anything else I have to do to the EFI? I've been told I would not have to worry about it and that I would have to install a EFI tuner. Which is correct?

i had the same setup and had to install a sert to get it to run correctly also the added benefit of the tuner is the heat. it makes the bike run much cooler a big benefit cause i sit in traffic alot!!!

you dont need to do anything to the ECM.....if you're worried about it though just get the dealier to flash it with the stage 1 download; it'll run you about $175 - raises the rev limiter....not sure what else. Thats the exact set up I have (Ruch with the 1.75s, SE Stage 1 A/C and the stage 1 download; bike runs great; no problems).

The dealer told me that you need to get the bike on the dyno to get right air/fuel ratio for your bike.There is no maps who will "fit" perfect general,every bike has a differernt tuning.

with the pipes already on , if you rather not spend the coin you don't need anything else.If you add the high flow A/C to the mix you def. have to richen your air/fuel ratio. Doing this will cost you about 500 t 600$,and you will not realize any true performance gain maybe 1 or 2 HP. I bet it sounds and runs great as is.that's all you really need.
Mine ran fine with A/C and rush 1.75's +Xied's--> the cheap and dirty fix! And I'am quoting steve mullen there owner of nightrider and inventor of the Xied's. He told me that on the phone! But I found it had lost some low end torque ,and had some decel popping so I got the stage 1 download.it's fine now , but the 225$ for the download is gone forever.Steve told me about the company which designs the software for HD,and it's available for purchase, it's around 500$, but you can use it as many times as you want,and on as many bikes as you want,which is good so you can always do further upgrades and just re-tune! You will need the use of a laptop computer.
I guess the in-between cost is the tuner which alot of people use, and even though you would think the HD sert would be great,you can only use it on 1 bike. silly considering it's cost.

But I'll never have to buy another tuner no matter what I do to the bike.
