I'm having surging issues at idle and at light throttle in gear. Base fuel should be very close. Have reset TPS, changed MAP sensors, adjusted Pedal vs TB Table, both WBO2 in the truck match. When it surges, AFR surges from 12.5 to 16. Base Fuel Table adjustments don't help anything. I have tried most of the base calibrations/Global Folders and they didn't help.
