I bought a f250 6.7L diesel with a dpf delete, not knowing I tried to add my bully dog tuner to my truck and cleared my delete tune on the truck. now I am dead in the water. what next
What tuner is it? Most tuners save the old tune in the stock location. You should be able to return to stock and get your old tune back.
That being said your truck should start with the new tune. If it's looking for the DPF it would just throw codes.
