The FAST DVD "Taking the Mystery & Intimidation ouf of EFI" is mainly geared toward the new XFI system. However, it will help with tunning features. Yes, alot of the tunning is done the same with the old system and the XFI. There are going to be extra tunning features with the XFI, but any little help for those that have a FAST system and no idea what to do, is always a plus. Just remember, there are some features that will be on the DVD that the classic system cannot do, but it would give you also an insight in to the XFI, incase you ever want to upgrade at a later date.
You can either order the DVD from FAST themself, or any dealer. The part number for the DVD is 307061.
