Torque wars continue in the diesels

I will also note that the reason for torque management is not just for the drive line. It is also mainly to keep from popping head gaskets due to high cylinder pressure. Combine the quick boost from a VGT, increased timing, and more fuel at lower rpms and you have a recipe for a popped head gaskets. Big power at low rpm is also very hard on the rods. Ever notice how head gasket failure was a common issue with the first few years that GM(LLY), Ford(6.0L), and, Cummins(6.7L) added VGT's and how torque management became a complaint shortly there after? Non-VGT diesels do not have to deal with this as much.

This is also probably one reason why 2015-16 VGT 6.7L Powerstokes felt a little slower of the line than the 2011-14 non-VGT Powerstrokes since Ford did not have to utilize torque management as much in non-VGT engines.

Having had a 2001.5 with a loose stock TC and a 89 % DTT, and then a mis-match loose TC on second rebuild, which was swapped out for a tighter one, I have to say my 2015 Aisin is not loose. I would say it is about right for towing and bobtail use.
