After VTT modification

The MAX eng tq is less than the eng tq yet theres no pulling timing, or closing the throttle. Thats why I am confused. I attached 2 logs, before and after VTT modification. In both instances the max eng tq gets exceeded around same spots.

I have read almost every single thread, and have seen your posts here and there. I am well aware of what struggles you have seen, I am assuming it is with that ATS turbo vehicle right? I noticed the pcm pulled boost AND timing if i remember correctly when max eng tq was exceeded in a screen shot of the log you had posted. So this is why I am trying to build on this discussion.
I have also noticed that modifying certain coefficients such as the MAP or airmass yields drastic changes even with the same amount of % added to the torque tables on the exact same spot. On this particular setup the change to the MAP yielding drastic changes to the MAX engine reported, whilst a change to the AIRMASS coefficient yielded minimal changes in max eng tq value. So max eng tq is a hard limit, why didnt it limit this vehicle on the log attached? In fact I have logged several trucks and they ALL get exceeded even factory. Straight up confusing when people say ignore it then others say dont ignore it and tune your VTTs.

I've read super old threads trying to figure this out, you are always in them. Did you ever get to the bottom of this?
