Heya,
Can't figure this one out. P59 411 with 3 bar OS, speed density.
Whenever I get to a point that the pcm calculates 2.4g of cylinder airmass, it goes into REP and kills the pedal until the car restarts. P0068 tables have already been maxed at 4.1.
2.4 is pretty damn high. Are you sure the airflow models are correct? Do you have a log? Make sure you are keeping fuel pressure at wide open? I ask because if you are loosing fuel pressure and have made up for it in the tuning, maybe unknowingly, you'd have this type of situation.

You're exceeding a hard coded limit in the PCM. You'll have to scale the tune
Wouldn't that be something like 1100HP, if accurate?
IIRC, something like 15psi of boost out of a 76mm single on a 5.3 has pegged out an 05 model truck PCM in some previous logs for me and I had to scale it
