The Fast EZ is ok, the handheld programmer leaves a lot to be desired in my opinion. Buy a cheap laptop $100-200. It doesn't take anything special. Actually I feel like Windows 7 is about as new as I like for all the tuning software out there. I would step up to a XFI Street. FAST has some very knowledgeable tech guys. If you get a tunable system and have an internet connection help is way simpler to get. Let me know if you have any other questions. I have used pretty much every system out there.
