edit**** my stock tune file was lost in my old computer and my current OS is already a 3 bar. is it possible to reset the ecu to stock settings using tech 2? at that point with the stock ecu, I could properly 80e segment swap, then switch back to the 3 bar OS. im trying to avoid wasting yet another 2 credits on something that doesn't work out. ive heard of tech 2 working?
