I can't seem to figure this out. The trims during a drive are pretty good in the -2 range but at idle they drop to -6 to -8. The car has stock cam with just headers and blackwing filter. I dropped the VE in the idle range but it didn't seem to do anything. Why didn't the VE change the fueling any? Any idea what I can change to get the idle leaned up some? Everything else looks to be good.
