Looking to buy flashscan from a reputable seller, but i dont want to run all his tunes all the time. im looking to run a few of my own tunes for sled pulling etc.. If you purchase tunes for a dsp can you save and remove a few of the dsp positions and write your own, leaving one or two pre tuned ones.. or do you have to retune them all with stock and start over?
vehicle is a 06, with a current efi tune, from unknown tuner, purchased the truck that way.
