WOT boost

[Brandon Rogers]

Thanks for the input-
I don't know if I can monitor the O2 sensor while driving--it is however,
new.  I should have set Duty Cycle is set at 43-50% when idling--those words
escaped me when I posted.  I wonder if the fuel pump is aging.  My system
and control pressure are fine, however maybe at high rpm they are low.  ??
Other ideas??
