Ari,
Are you having drivability problems or just noticed a different A/F ratio?
You swapped to 3 in intake tubing? Isn't that larger than the flange on the MAF?
I'm wondering if the size difference is causing he air to tumble and cause a misread by the MAF; it thinks you are getting less air & leans out the fuel to compensate

clip ===========
get a peak of 4.54-55v from the maf @ 7400rpm (was 4.59-61v with old intake)
o2 sensor shows 0.85-86v,
