2024 Chevy 3500 verses 2023 F350

^^^ The High Output is supposed to be putting out about 150 more lbft of torque at bottom end of the power curve (so we should be able to expect at least 45 more horsepower at 2100 rpm and 25 more horsepower at 2600 rpm). Say 35 more ponies on average from 2100 to 2600 rpm. At 10,000feet of elevation maybe that 35 more HP would be more like 30 more hp. Considering the additional 30 hp and the fact that this trailer was 1500 lbs lighter than the trailer the 2020 pulled up the hill, the high output should have been able to shave nearly a minute off the 2020’s time. I had guessed it would have had a time of just under 9 and a half minutes. Maybe the warmer temperatures played a role or maybe the 2020 truck that TFLT used was an over achiever? Compared to the Duramax it looks like maybe this 2023 high output is an under achiever.
