Was able to reach out to the previous owner to get some history on our new to us 17 GT350. He said the original owner was the attorney for a North Texas Ford dealer who sold it and bought a GT350 R. Second owner is a city manager for a town in North Texas - only those two had driven it and it was always babied, only washed once and always kept detailed and spotless. Here is the dilemma - PO took it to Dallas Mustang to get long tube headers, X pipe & JLT cold air. It was tuned by them but they forgot to give the SCT X4 back to the owner. When he remembered to go back and get it, they were out of business! Because of not having the tuner, we don't have the stock tune in case we need warranty work. The dealership we got it from is family so I could get it flashed back to stock if we needed to but the JLT requires a custom tune - flashing back to stock would destroy the DM tune, so I would need to buy another tuner and find a reputable tune shop to build me a new one. PO reported no oil consumption in 4,000 miles and the car runs perfect now so I'm thinking if just letting it ride and not spend $6 - 700 unless I have to. Thoughts? Thanks!!
