If everything mechanical is right, it sounds like a ****ty tune.
The 02s aren't read at WOT because the computer is in open loop and reading off of the fuel/timing tables that are programmed, so it's not the o2s. If the car was acting stupid driving around at part throttle, then it may have been your o2s, but not at WOT.
You can always gain more power/better drivability with a dynotune.

I did find out part of my problem today. For whatever reason it seems that I have lazy o2 sensors. They like to read lean even though the car is running so rich it almost makes your eyes tear up. But I really do not want to put $100 worth of o2's in the car if they are just gonna get ate up again by the tune. Does anybody know of any good dyno tuners in the kansas area, maybe kansas city? And if so, how much do you think a deceint tune will cost me?

Well I went to the track Friday night. Car did not even seem like it was pulling as hard as it could. But my times were so bad for what I got done I have no idea what is the matter with it. I hooked it up to a scanner earlyer in the week. And for some reason the computer thinks that it is running lean so it just dumps fuel into the engine. But in reality the enigne is running rich. Even the spark plugs were pure black. You can even smell the gas the whole time the engine is running. But I beleive it is some sensor that is making the whole system mess up but I want to know what you guys think. Any help would be great. Here are my horrible times
