I just installed the thing, quite easily actually aside from losing the ball bearing and more, now my biggest question to those guys who have experience is what regulator pressures should I be setting this to? My goal is around 75-79 FPE of energy and when I dry fired it god damn did it sound different, it even did the swoooosh sound from front to back reg and I believe I'm @ 125 PSI on my front reg? Does anyone have any suggestions? I don't have my much room to work with, my rubber mulch is running out and 60 FPE went through it once actually so this REALLY scares me lol. I'd like to pretty much get it anywhere in the 75-79 in the first try. I'm thinking 150/125? Forgot to mention, I've never regulated it, had a company tune it, it's shooting 58 FPE I believe with 29 grain NSA slugs. and 60 FPE with FX Hybrids. The back pressure monitor says 125-130, maybe I'll leave it alone and take a test shot to see what it does even now?
