MAF Sensor, o2's, and n75 not reading

[jolio1994]

I'm running a single HPX Maf in place of the stock 2x Bosch units for my single turbo setup (Currently wired for G70 MAF). The HPX pigtail is wired as it should and I'm getting +12v at the green/yellow wire, engine/chassis ground at the green/back wire, and have tested and read continuity between the green signal wire on the MAF to pin 29 on the ECU connector.

VCDS still reads signal too low and measuring blocks 2 and 3 both show no activity for the MAF's. Also having fault codes for o2's and n75 signal too low as well... my tuner and I are stumped.

Fuses are out of the question since I'm getting power to the MAF, no short to grounds or anything weird aswell.

And help or suggestions are appreciated, I need to open this wastegate up!
