Tell him if he pays for your other VIN license (and/or however much else you want) you'll turn the codes off for him.

Read his stock tune, save it in a few places, then go in and change the DTC enablers to not reported. Flash it back and you're done, maybe 30mins if you havent touched a gasser before. If he wants you can remove a little Torque Management too and firm his shifts up.

Cant answer that for you, depends on your state.
