I certainly don't qualify as an expert, but I happened to ask my mechanic--who is one--his opinion of both systems. He was trained in Germany to work on the MFI when it came out, and he much prefers the CIS. There are many more "wear" parts (ie. butterfly valves) on the MFI, and as the system wears, it becomes more and more difficult to run smoothly. He finds the CIS by comparison, more economical and easier to work with. He feels both systems are good if in running order, but he prefers the CIS. Again, I really don't know specifics, but this was one opinion from one who I respect, and will get this thread started.
