car bogs at around 10psi

[primodts]

i have a 95 gst with a 6 bolt swap, big 16g, hks ssqv, hks cams, and apexi n1 turbo back exhaust and the problem i'm having is when i'm driving and i step on it and the boost gets up to about 10 psi and it starts bogging really bad and won't accelerate anymore, i think the problem lies in the rear o2 sensor being ripped out so the wires are just hanging down from the exhaust , i went to replace it but i wasn't sure where to hook up the new one, i found a harness up where the old o2 sensor used to be hooked up but the wire colors didn't match, they were blue, yellow, red and black, and the o2 sensor had 2 blacks a red and a white, can anybody help me locate where i hook it back up , or any other possible solutions the problem

Are you getting a CEL? If so have someone toss a logger on it and find out what the issue is.

Could be your plugs and wires. its not uncommon to say the least.

the rear O2 does nothing on our cars, its only there to tell you if your cats goin or youre runnin too rich or something but as far as performance it does nothing, ive been running with no back o2 for like 6 months now and no problems are caused besides the CEL which i just clear with my logger
