TBI....To swap or not to swap

My question in this:

Has there been enough technology in the the past ten years with TBI's and injectors to warrant a new throttle body unit or injectors for a '92 RS with 56,000 miles?

If I do the change I would want to move up to a 650cfm or slightly higher.

the throttle bodies havnet changed. although you probably dont need a bigger throttle body yet it might help a little

Flow matching isn't as big a deal on TBIs as it is on any type of multi-port fuel injection.
