The SES light from the ORY shouldn't affect performance. Unless you are commanding open-loop, you should be in closed-loop while just cruising. P/E mode is open-loop. Did you try reseting your trims? Where are they? Are you getting any other codes besides the ones thrown by the rear O2s?

horist

normal driving you will always be in closed loop unless you turn the car to open loop always

Closed loop uses the O2 sensors to maintain 14.7:1 or so AFR
The rear O2 sensors don't impact performance so they shouldn't matter

As for tuning the rear codes out, in the Engine DTC section you just disabled the codes ... scan the car and see what codes its setting, or just disable anything that says bank 1 sensor 2 or bank2 sensor 2

As for running worse... can't tell anything w/out some logs of what the car's doing and what you mean by running worse... need more details to even try to help

whoops ..sorry

i ment open loop

i havent done anything with the car in a while...so my tuning and thinking is off
something is off... i gotta go log a bit more
but it doesnt seem to have the power it once did, and it is loosing power and breaking up a lil around 4500ish to 5500 ish...then power comes on again til rev limiter @6200.l i'll check some more things and get back.
its stock with procharger w/ 10 psi, headers, ORY, 42's
