it's married so it's worthless unless he can unmarry it. SCT will charge $150 for this service so, you'd be up to $200 and still need to buy a tune.
If I were you, I'd buy a tuner box (SCT x4) from a trusted tuner like VMP, Steeda or Lund. You'll get a tuner pre-loaded with quality tunes and you can look up video online on how to install the tunes. Hope you have a battery charger or jumper cables and a second vehicle. Not a good idea to just put a tune on a car supported by only its own battery power. It drops even a smidge below 12v and it'll lock up.
