I am having my car dyno tuned and will no longer be using the SCT tuner or my Brenspeed tunes. Can I just unload the Brenspeed tune from my car and then sell the tuner? I bought it with the C&L racer intake which I am keeping, is the tune specific to that intake? If anyone has bought a used one please tell me what you paid so I have an idea of what it should sell for.
