Check for vacuum leaks at the intake manifold. My MSD was leaking and my idle trims were +30%, but above 1500 RPM the trims were good. Small exhaust leaks shouldn't cause your trims to be that out of whack.

Mystery solved.. The collector was leaking and it appeared it was drawing fresh air with the pulses causing the wb sensor that sits appx a foot behind that location to read lean. I put a heat bandage and the clamp over that and now it reads normal again. I am disappointed in the American Racing Header collector fitment into there long exhaust cause both sides leaked. Even tried new clamps but still leaked. For that much money I expected a better fit(no leaks).

I believe this is why CSP worked with stainless works to create a header that has a flange seal, fits like a glove, and also works with the stock plug wires. Most headers require aftermarket angled plug wires to keep from touching the primaries.
