I have a 2015 TZX 190 with 150 hpdi 23m prop. I have messured the prop centerline at 3.5" below the pad. Will I be able to find any significant gains in speed or milage moving it up some?

3.5 is a good starting point for most boats. Generally they do end up moving up some but it depends on a lot of factors.

What are your numbers now, top end, RPM's, plane time?
