Need advice...
and think about it! Your best bet is to either find a shop that can do it, or find someone that has a tunner that can help you out. Personaly i have EFI live and would be glad to make some adjusts for you, i'm going to school in boston though which would be a bit of a drive. Only thing is you would have to pay for a license becuase i would lose one by flashing to your computer.
Hope that helps let me know if you have any questions
