Ok, here's what I found. Playing around destroying the speed nocks taking them on and off, I gained maybe 2fps. And bowtech pretty much had it nailed from the factory, when I put them where they put them, I got optimal speed. I went from 253 with 430gr total arrow wieght, to 255.6.

No big deal right? Well, I did get rid of the string buzz. Lots of work for 2fps, but I had to quieten down this bow. Still want it quieter. Willing to sacrafice speed. So installed the hush kit back on. Wished I went ahead and bought new, but I slid the old ones back on. Two on the cable and two on the string. Good news, it only dropped me to a good 255fps. Compared to the leeches.
