What is the difference between the HD Stage 1 EFI modulator 'flash' and an after market EFI programmable modulator?
The Stage 1 reflash from Harley raises your rev limit 500rpm and up to 2004 also altered the fuel curve slightly over the stock ECM. From 2005 and up all it does it raise your rev limit. This is a one time download that is not able to be altered in any way.

See? I don't make this stuff up. Now, it's entirely possible that Dynojet is being a bit parochial about all this since they're trying to sell Power Commanders but, I dunno.

That is wrong. Fact is FXD models are 07 and up. also the 5500 rpm is raised to 6200 which is 700 rpms - not 500. Timing is advanced and the map is redone to account for the higher VE. If you need do not understand VE, you won't understand nor comprehend remapping. The open loop is rich from the factory (13.x to 1), closed loop is 14.6 to 1. You are in open loop in heavy load conditions such as acceleration. Close loop is used under light load conditions such as cruising. Must understand how fuel injection system works to realize all the misinformation thrown around here. I WILL STICK WITH THE SUGGESTIONS OF THE 3 HD MASTER TECHS THAT I KNOW THAT WORK ON THE BIKES AND OWN THEM. My bike with stage 1 remap, heavy breather and SE slip ons runs great without any problems.

Just trying to provide some advice so you won't be making the same mistakes throwing away money many of us made in our youth. If you are doing making these mods for performance, you may think you are happy for awhile, but you will definitely be much happier spending a few more $$ for a proper tuning kit and use it on that late model bike. If its just a style thing and just a ride, it doesn't matter.

He could be wrong and you could be right. I honestly don't know.
Just trying to help.

The HD tech data says 6200 RPM.
Verdict is in. Rush 2.0 slip on muffler, Arlen Ness Big Sucker AC and HD recalibration makes more noticeable power and runs cooler. Just took her out for a test ride.
It was worth doing.

Initially, that's what I wanted to do with my bike. So off I goes to the HD dealer and the Service Writer about has a nervous breakdown, telling me that it's suicidal to just do a remap, download, or whatever the hell they call it with an A/C and exhaust mod.
Even the actual tuner himself got involved in the discussion. I got the impression that the Stage I remap wasn't even being done anymore. That Harley pulled it.
So I don't mind being educated on all this business. At all. I don't have a dog in this fight, I just wanna know what's up with what. I'm like you, I just want a little more power, a decent sounding bike and mechanical reliability. I also wouldn't mind replacing the stock A/C as it looks kinda big and gets in the way.
Thanks for the feedback. Looks like I'm back to square one. Again.
