Go log a run on the atap/efilive/tech-II. If the injectors go over 85% they go static. which basically means anywhere from 85%+ you're injectors are wide open. I doubt it would make that much of a power loss though.
Any reason you're revving that high? my stock car (lid/catback) didn't make any power past 5500rpm.. or did i read that wrong that your car isn't stock?

I have o2 sims in the rear banks and the front banks show activity. Is there a way to tell specificly that they are bad? Corvettes of Houston, Speed Demon, and MTI have all seen the o2 sensors im sure on the tech2 and none have said they are out of wack.
Regardless please relay your experiences they cant hurt

well, in my case, the O2 sensors showed "normal" activity and even passed a daignostic test. The only reason I found then was that I got tired of screwing with the tune. I had replaced the plugs, wires, and had the coil packs checked. So, i put my car up and took out the O2 sensors and replaced them. after that, everything worked perfectly.
If you still have the rear O2's and they're in good working condition, it wouldn't hurt to swap them ....
