The FX manual says to never shoot your impact below "regulator" pressure. But they don't clearly say which one. Reg 1 or Reg 2? I sure hope it's reg 2 because that's what I've been going by. I shoot until my tank pressure is just above what I have Reg 2 set at. However, I just watched a video about tuning and the guy said to not go below reg 1??? I'm so confused. If it's reg 1, that would drastically cut down on the number of shots.
