95 Z28 M6 - CC306 w/ported factory heads
338/326
Note: I bought the car as it sits and have only tweaked the tune, so I don't know the exact flow specs on the heads. Stock bottom end, 119k. AFR is 12.9-13.2 at WOT. Thoughts? This seems awfully low compared to what I've seen from this setup. I have Edelbrock shorties, a high flow cat and an unknown catback (Magnaflow I think?). Peak torque came on at ~3k and stayed there, power climbed until redline. One theory is that I might be choking it with the shorties. Opti is newer, plugs are new, wires are good. Car runs great in general.
