etc

i have an o2 1500hd w/ a whipple s.c, it has a piggyback computer and an electronic bypass. that has'nt worked right since i got it. i have tried everything i can think of but still have the same problem. the whipple computer sends very low o2 signals to my pcm at anything ovr 60% throttle and sets low voltage ses. i've installed 43lb inj's and disconnected the aux inj's. here's my theory; since i need the computer only to control boost can i rewire the whipple to read the signal rather than intercept and modify it ?. only three wires are intercepted the maf and both front o2 sensors, if i wire the pcm back to stock and tap these wires, does anyone know if i would experience a signal voltage drop that would corrupt the info to the pcm ? i have edit and efi live to tune for not having the piggyback. thanks for any input.
