It idles smooth at 850 once warm and I went 75 below that with the throttle stop screw. Should I bump that up to say 800-825? I wasn't sure just how quick the IAC can react.

U should also work on timing and fuel tables to smooth things out and avoid any choppy transitions of both.

I'll check them again and see what it's like down there.

Also, the throttle follower tables should reflect the IAC steps u r actually at for idle.

I don't believe these follower tables in the XDF I'm using.
