looking for a price on a new tune. 06 cummins, built auto trans, air dog lift pump, stock turbo and injectors. i do not have an efilive loading device but do have the ability to flash the pcm with a pass thru. i do have the 5 position switch. would like a tow tune for one of the positions performance for the rest. current tune has all of my shift points and almost 3k rpm WOT. Thanks for any help
