I want to do the tune using a cable over the internet. Here is the what madz28 has to say. "The email package consists of programming through email if you have your own cable. It will cover all the modifications you have currently for $75. This service is for one car. Updates are $25.

Note: Use this service only if you are confident that your laptop to PCM connection is reliable as I cannot take responsibility for failed uploads or a bad connection."
Do i need anything besides the cable or is it all set up for me? Has anyone done this and would you recommend it? I have a FMU because of the supercharger, do i unhook and remove from the car? I assume the tune would make it unnecessary.
