How much is this typically worth? My friend has a mini max with H&S ****** tunes on his 08 6.4. He is going to trade the truck in on a 2016 he likes, so his ****** stuff will be available. I know these tuners are getting harder to find so I'm wondering what to ask for it. He has the pod, mini max tuner, and downpipe back exhaust with sensor ports. Would make someone with a 6.4 a good ****** kit for a stock truck.
