More damn issues.. Any input?

So went to finish tuning this weekend an all of a sudden once i get there the wideband does the whole reading lean issue again..

Can go WOT and right before i shift at 5,5-5,8k rpms the wideband goes complete lean, the car does not lose any power, no kr no codes.. Im so stumped and so is my tuner.

Ive watched fuel pressure and it stays 55psi even when it "goes lean" so i know my pump fine.. And if it was a or a couple bad injectors wouldnt i get misfires and codes..?
 


The only thing more reliable than your wideband in terms of knowing how much fuel is going to your motor is the data value generated from:

IPW vs RPM vs Fuel pressure.

If none of those change sigificantly, then you probably have other issues.
