I recently did the HD Stage 1 download via the HD Pro Street Tuner. I have the SE Street Cannons and K&N filter. This map seems perfect with this set-up.
It did increase idle speed to 950, and when coasting to a stop, it revs to 1250 at 10 MPH until stopped. I didn't previously have stalling issues, but this is probably what they addressed with the idle speeds.
BTW...the FP3 can not be sold in California, so I assume that means it's not CARB/EPA compliant.

I have the SEPST, street cannons and the Ventilator breather. It makes more than adequate power, sounds decent to me and averages 55 mpg at 60 mph rural roads cruising. The street cannons will bark when you get on them but are well mannered in town. I don't care about setting off car alarms as I ride by.

How do you guys get idles down to 950? I did the ad5 stage 1 but have s&s mk45 45s. Only difference. But my bike idles around 1050 and as far as I know, you can't adjust the idle speed manually with the SEPST.
