Probably missed a limit table you or a DTC code, or something in the tune isn't quite right, I am sure Trent can get it all straightened out for ya if he tuned it, if you tuned it then recheck all the tables.

Is it not throwing any codes? If not I would say you have DTC turned off that might need to be on
