F.A.S.T EZI Good/Bad? anyone?

I've been running SDS efi on my 2.2 turbo shadow since 1999. I have now changed to a 2.4 dohc and still using the same SDS. This is my daily driver that gets 10-15,000 miles a year. I also have the same set up on my 318 swapped '87 Dakota. It sees a lot of daily use at times also. While these systems where good for there time, there are much better systems available now. I'm planning to change them both to Megasquirt. For the money and features I don't see using anything else. There is also a dyno shop in the area that is familiar with these. I would prefer a system that has a lot of features (AIS and fan control, 2 step, sequential injection, etc.).
