The sf3 just comes with very generic tunes that I wouldn't recommend, I'd recommend getting the X3 and just wait for the custom tunes. Also Eric at IDP is an amazing tuner, tell him Robby from the GPDA sent you, he'll work with you and usually get you the tunes faster then anyone else.
kinda figured i'm probably going with viv cause it's one price and all the reg tunes i want, only cost would be if i get injectors or turbo and need extreme custom tuning. plus she's been great to talk to and fast email responses
