Long-Tube headers. Can the 02's read properly WITHOUT aftermarket computer?

If you have a tuner around you that can datalog and has a loaded dyno I would duplicate the issue on the dyno and see what is going on.

Reading your symptoms it sounds like a problem in how the vehicle is tuned for the injectors. I would not think it is O2s. Likely just poor a calibration.

Glad I brought this up with you guys. I am having the tuner look at this next week. Strange..all this time I thought it was lt's and could have been totally wrong.
