I take my car in to the dealership every 3000 miles to get an oil change but this is going to be the first time that I take it in with a tune installed. Because of my mods I cannot put my computer back to stock. Should I tell them that I have a tune on the car so they dont do anyting with the computer? Also I cant do the oil change myself. I am no allowed to at my house. So that cannot be an option. Thanks.
