Cougar5.0,
Yeah I already have worked on that part, however some of this may be due to the manifold filling routine. I think your right about the lower RPM load stuff. I removed 2* timing from my 3 lower loads out to 2000 RPM in the timing tables and so far it looks promising with much better off idle response and low RPM lugging....looks like I'm making progress. Time will tell.
Update: Removing timing at lower loads is fixing the issue. Almost there!
