Have you tried to richen it with the chip yet?
Put the translator back to zero on the WOT and try richening it with the chip if you haven't tried it yet. I find the chip has way more control on WOT fueling.
Also your base setting, is that on the correct size MAF you have? I've seen that a bunch of times also, people put it on the 3.5 setting instead of the 3" sensor they have.........
