Not sure how they mapped the tranny to the torque, they might have a performance selection, not sure, but here is a list of problems that come with the diesel purchase.
I find the exhaust stinks worse than gas, that's my opinion.
The fuel pumps are usually oily and stink your hands up and this further gets into the vehicle and on your clothes every fill up. If you enjoy this smell than all the power to you.
Diesel costs more
The maintenance has proven to be more expensive
You have to add def fluid
Diesels don't heat up the cab in the colder climates or defrost your windows as well as a gas motor will
The motor costs more so you never get your fuel savings back from the pump
They have poor acceleration in comparison to a gas motor so even in emergencies your truck is flat footed in comparison to a gas motor
There are less fuel stations that actually carry diesel, this can be an inconvenience
They pollute the air with N0x which is a soot, hence the smell and this is not regulated since diesels have never become popular for good reasons
They are suited for commercial/industrial use as a profitable prospective vehicle proven not to suit residential use by consumer support since they make up only 1% of the vehicle population.
