I have a 2014 CM2350A that's been fully deleted and I wanna change just the torque on it can I do that with just dataplate or do I need to go more in-depth then that?
It is much more in-depth than that. Multiple tables, fueling limits, and many other changes will be needed to change torque / HP.
The data plate is just an advertised value. It means nothing, it is just what is showed to the user in INSITE.
