I'm pretty sure this is related to overfueling. Question is, when setting up a new engine combination should the AE tables all be zeroed out? This was a base tune for a turbo SBF and I keep carbon fouling the plugs on every cylinder. Doubt it's coil or plug related, as with fresh plugs it will run great until they get sooted up again. Also, with the car running should I try pulling fuel and if I do so, should I be focusing on where the live cursor is floating around or concentrate on a larger group of cells surrounding the cursor? I'm pretty sure it's just getting way too much fuel or an AE table is setup incorrectly.
