Oops, my bad. You mentioned AFR's being 12,13,14 across the board. Please tell me that was NOT under boost. Assuming that your fuel system is up to par, I would start with one, maybe two steps colder on the plugs and gap them down. If 93 is available in your area, see if you can tune it safely w/out meth. 11.5 is as high as I would like to see on a street car for afr's, tuned safely.
