thanks guys...newer 300zx fuel filter, plugs gapped at .028, injectors are brand new with flow charts with "very short lag times". checked the FPR last year when i bought the car, im 90% sure it was like 42-43 psi, where the tuner told me to keep it, bought the 02 sensor new last year with about 4-5k miles on it. the extra leanness came after the new injectors/tune. i did not clean the MAF. i'll DBL check the FPR tomorrow and clean the MAF, but they seem fine while cruising and at WOT.
