EJ fuel injected or Weber and Escort distributor

Does anyone know the approximate HP difference between a '95 fuel injected EJ22 and one that has been converted to a Weber and an Escort distributor? 

Tuned correctly it will be the same. Tuning an EFI car is much easier. If you're already using a stock ECU that is correct for the application, no tuning needed.

Doing a factory efi EJ22 install is much easier than fabricating parts for dizzy and Weber in my book.

I would love to see evidence that a single or twin barrel carb can get the same performance as a MPFI setup. Carb vs SPFI I'd agree, MPFI I doubt very much. Even Subaru's own EA82 shows a marked improvement from carb to MPFI (9kW, minus what was gained from increasing the C/R).

Wasn't just MPFi that changed the EA82 MPFi, it got quad runner intake manifolding and twin intake port heads

I would imagine the ECU was more powerful and has larger maps. Also the power gain could be entirely artificial to justify the increased cost.
