Believe it or not, I actually tested this on my '86 (back when it was a 6-port) and on my '91. The car feels a lot faster with the ports wired open, but it is truly slower (as measured by my G-tech). I didn't believe it at first either, but perceived acceleration can be deceiving.

It might be worth installing an air pump and reconnecting the 5/6 port actuators, it will also help your fuel economy (17 mpg highway wired open vs 23 mpg hwy functioning).

This advice cost you nothing, but it would be a neat project.
