Looks to me that the GM de-fueled (cutting power) because EGT's were probably getting too hot. Big difference between initial power and sustained power.
The GM's 445 horsepower is barely sustainable towing that heavy of a load with a stock turbo in a deleted truck without getting the EGT's too high so I doubt an emissions intact truck can sustain that. It would have to de-fuel to keep the EGT's in check.
You may be right but isn't it surprising that the 2015 Duramax out performs the 2017? I would have thought the turbo on the 2017 would pump more air and be capable of higher power with lower EGTs.
