I can't figure out why i run rich at idle, but i lean out at different rpms... This has been causing my problems.
Keep in mind i am running 73mm c&l MAM with 24 pound injectors, fuel pump unknown.. kirban AFPR

Make sure you don't have any vacuum leaks. Those kind of leaks will cause all kinds of weird problems. And like said before your computer could be going crazy.

Fuel pump unknown?? Might have answered your own question. Could be a higher flowing pump, just worn out and unable to provide adequate fuel when needed?
