Spacers were effective with several carb manifold combinations and some TBI set ups. The main advantage is it allowed better atomizing of the fuel air mix as it entered the manifold by increasing the size of the plenum.
With a SFI setup the injectors are downstream of the throttle body so the fuel and air don't come together before the cylinder head. If user notices an improvement after installing a spacer on a SFI its probably because there was a vacuum leak at the TB/manifold flange.
Just my $.02 but I've never seen an independent dyno test where the TB spacer made any improvement on a SFI engine.

Benifits are usually only seen on all-out competition engines. Street use engines will only see fractional improvements at best.
Phenolic Upper to Lower intake spacers don't weigh that much.

That would require paying attention as opposed to knee-jerk posting...
