question on dyno tunng
EFI tuning is conceptually the same, but every car works a different way. No one on this forum is gonna speak for the quality of this shop unless they've been there so call them up and ASK. If you feel like they are BSing then better safe then sorry. Otherwise, get to know the LS1 system a little and go into the cage with some weapons, so you can spot the BSing should it occur.
My first impression is no they won't give you the perfect LS1 tune, but who knows...
