Bought some 24 lbs injectors a few weeks ago along with a maf.

They are used Injectors and have 45k on them, I replaced the caps and o-rings.

MAF is a 75MM Pro-M pro flow calibrated for 24 lbs injector.

I threw them in this morning, all was well, popped right in. I set them in correctly.

Started right up, I let it warm up to operating temp, and took her for a spin.

It runs great through all gears, but if I WOT, at any RPMS, it chokes up.

I took it to a friend (who is a certified mechanic), and he put a fuel pressure gauge on it and took it for a spin, 33 PSI WOT. So I eliminated the fuel pump as being the culprit, so I went on to the MAF, I tried clocking it at all positions, and it still chokes up WOT.

He told me to disconnect the MAF and drive it. I did so, and it still choked up WOT...

What could be the culprit of all this? I also pulled the codes and they were:

54

96

29

66

Please help, I am in a total slump on this issue.

Oh not to forget, it is an 88 GT, explorer intake, stock tb and spacer, cold air. Originally a speed density car, converted to MAF.
