that way my PCM is stock and anytime I remove the livewire it goes back to stock.
the goal is to get rid of the tune that is on there without going the ford IDS route to get flashed with a stock calibration.
just trying to get the PCM bone stock so there are no floating gremlins from the past tune.
the existing unknown tune is too hot for towing and i want to make sure the truck is safe for towing.
