I may have missed it, but I didn't see a barometric pressure reading to indicate you were in table 'C'. Is it possible the truck was running in timing table 'B'? Also check the limiting table and modifier tables.

I thought the baro would be the issue but they are not even close to those tables. I've check the modifiers to see if there is a match and nothing.
