The '06 flash didn't affect my rocks-in-a-can problems and I bought IDS as soon as it came out. It provided a huge improvement and no more complaints, along with a much smoother drivetrain. The 5th-gear noises are still there but hardly noticeable anymore. I attribute this in major part to IDS and the Redline SPH gear oil I've been running.
I guess I'll drop by the HD shop tomorrow and ask about it.
So the high-idle is still there after the last re-flash? That isn't encouraging. My bike was on the Digital Technician in Sept. '08 IIRC to activate the security system I added, but I don't know if they did a re-flash at that time. I would tend to doubt it since I didn't ask for it and they didn't say anything.
