New guy and my name is Jimmy and I'm new to the diesel world.
I just bought my first diesel.
It came with mods EGR delete DRD tuned MM3 tuner 5 in exhaust back and cold air intake.
I need some info on what to tow a 15k fifth wheel camper in.
All I know about the tunes and tuner is it has a set tune for every time the key is turned on, and it has a few custom tunes you can change to 12v tune, whistle tune, lope tune, and a normal tune it may have more idk.
I've read you want to tow with your lowest hp tune and watch your trans and coolant Temps but not sure how to know what the lowest hp tune is.
Bear with me; I'm learning.
