I would lower the strut back down a bit. Sounds like the prop is running a bit shallow in the water. Make adjustments with your cog to get her flying level.

Timing change will make almost no noticeable difference in speed FYI. Hope you aren't expecting it to

Try a M445 or a X642 I got a considerable speed increase over a 42x55. I also run a degree or 2 positive angle on the strut with the same motor esc combo.
