bad 02?

[talstar]

Car is running bad at wot but runs fine at part throttle. No knock, but the scanmaster is showing lower 02s than it should. Boost is turned down until I get a new 02 in there. Just wondering if it is the problem.

possible but list all scanmaster values on that run easier to troubleshoot.

I don't have a way of doing that but everything else like looks fine. Going to check the fuel pressure when I get the my guage back that was "borrowed" a while back.
