Whats your LTFT like, If you maf scaling is out and your fuel trims are high in CL it can transition across to OL at WOT and the gap between commanded AFR and actual AFR can be quite wide.
When you first flash all is sweet as trims are reset, then after a week or so if your maf scaling is off your trims will be high and your AFR off .
Could be a lot of other things as well like exhaust gasket leak throwing off O2 sensor readings.
