I was logging a 6.7 tonight and noticed some varying readings. When first logging the truck ran smooth and the balanced vs uncompensated rates were very close. 2nd log the truck would stumble right after a shift. Rates were almost consistently off by 15 units. Logged the truck again and it started slightly off then pretty much matched back up. No more stumbling. We never even shut the truck off in between logs. I was just messing around with different pids. What makes up the differences in these 2 readouts? Is it a sign of regen? Anybody else notice this?
