I would say the Ineos engine is retuned to suit the application. The Ineos tune gives a high torque rise early. It flattens out the torque curve and give higher horse power lower in the RPM to perform more like a truck engine and not a performance car.
What I found interesting was what he was saying about the oil viscosities particularly the 0W-12 he mentions. Oil viscosity seems to be a contentious topic at the moment, and it doesn't matter what brand the 4x4 is. I had an interesting discussion with a Land Rover owner wanting to change his 6 cylinder Defender to a higher viscosity for towing and also have had similar discussions with several Toyota diesel owners considering similar changes.
