while on flat ground with cruise control set at 65mph the afr goes from commanded 16 to commanded 13. there is a very quick drop in timing instantly before the afr is commanded to 13 then timing goes right back to where it was but yet the afr does not change unless i made a big change in throttle or speed. abuse management some how getting activated ???

]NOTE frame 800-810 is the concern.

attached is the tune file in the truck and the data log from that tune file.
