Please help he if you can folks.
My Setup: Xvalve, Lvl 10 tunned with a nice loose fitting carrier, red bolt spring, ult with 5 shims (tuned for ver frame), SHP tank outputting max psi.

The problems.
#1. When I turn the air on, the gun decides to start shooting full auto. (i think ive fixed this issue by rebuilding the ULT, but id like to get more opinions).

#2. Im getting weird FSDO. For example, Ill shoot five times rapid fire, wait five seconds, pull the trigger and it chuffs with the bolt only moving half way. Wait
another five seconds after that and pull the trigger and it shoots fine. Any thoughts?

You are putting way to much air into the valve. You do not need 1200psi or whatever the tank is outputting into your valve. Try that setup with a 800psi tank and go from there.
