Twin 23 mirage vs mirage+?
 

I have a 96 PQ 270 laser twin 350 mag mpi’s and B1’s. I just finished up my hydraulic steering and am now able to get the boat to 69-70 gps safely at around 5,000-5,100rpm. I am running 23p mirage’s spinning out. Would there be any room for improvement on top speed going to mirage+‘s?

In my experience, the Mirage's tend to run 1-1.5 MPH better than Mirage Plus.

I had a 216 Wellcraft Eclipse years ago. Had a prop shop change the cup height on my Mirage (I believe from 0.060" to 0.080" like a Mirage Plus). I lost 2 mph, took it back and they reduced the cup to the Mirage prop and the speed came back. I think it depends on the hull, X dimension, weight and other factors. I know of a few people that were faster with a Mirage Plus, but most comments I have heard along with my own experience, favored the standard Mirage for Top End.
