Hi all. I just bought my truck used a few weeks ago. I bought it from a dealer and the previous owner had done all the mods on it. It has the full delete, turbo back exhaust, and efi live tuning. I'm admittedly green when it comes to diesels and tuning. How the heck do I go about finding what's in the truck for a tune and who tuned it? I do have an Autocal. I have not done anything except plug it in to see what functions are on it. I'd like to know how hot the tune is and if I have a copy of the original map on the Autocal, should I need to have any work done at the dealership. If it matters the manual idle is not active at this time on the truck, being in Minnesota I'd like to have that option. Truck is a 2008 2500 Laramie.
