Your hp reg was at 500!!!!!
It needs to be 250-300 otherwise you will blow your noid or worse! And thats why you were shooting way hott your pressure was almost twice more than it should be!
Bottom out regs, set hp to 250, adjust lp until you are shooting desired speed. If its not recharging fast enough take apart your hp reg and clean it out and lube it. If its dry it wont work correctly.
