I have a raceme ultra that I don't keep plugged into my truck(hate the look of a tuner stuck on the windshield with wires hanging off it), only used it to flash the ecm with rays tune. I'm happy with the results of the tune and don't plan on adding any power in the future so I want to recoup some of the expense of the deletes by selling the raceme. If I disclose that it was used for one VIN, can someone else use it to program their truck? Will they have to buy anything else like a vin unlock code?
