I to have a reputable shop Dyno Tune my Dodge.
I have the vehicle licensed.
I want to be able to have the capability to flash back to stock if needed, or possibly make changes if required down the road for future mods and the like.
What do I need to do in order to make sure when I leave the shop I have control of the tune?
Do I request he use my interface? Or do I just do a full read with my interface?
Thanks,
