LOL if you want to get shot by someone sure sell it
If you download a tune to it and put it on your car, it will only work with your car.
Now you can send it back to SCT and have them re write the program but costs a stupid amount. So you'd have to sell the tuner for a stupidly cheap amount or give it away.
But you do realize its quite stupid to sell such a nice peice.
And how much did you spend on all those mods ?
