Opening the hot idle comp is a great idea for WOT, but would hurt me with trying to richen the idle. I'll have to save that idea for later. I'll update this after I do some adjusting.
Actually I don't understand how this would help at WOT. It's just a small air passage. Yes? I
At idle, consuming 4 to 6 cfm, or maybe 8-10 with a high idle rpm, the compensator will flow a small but noticible percentage of that.

(It's not like a bleed into the circuit which alters the pressure difference and the density.)
