i just installed the tuner in my truck today i didn't change anything i just did the modify stock tune and turned off the DOD das this mean that my truck is completely stock except for the fact that i turned of the DOD. so i can still use regular gas and ex. like everything the same except the DOD? i wanted to do the 87 tune but I'm not sure what exactly it das to the car i didn't wana mess around until i asked.

Run the 87 tune, you'll get some more power and better performance, and maybe a little mileage gain.

For now yes, you are stock with just the DoD off.

with the 87 tune do i have to worry about anything going wrong with the truck like is there a higher risk with that tune? i don't have any modifications at the moment. I'm looking at an exhausts and intake but not any time sone

the tunes are designed for stock applications so you should be fine.
