Start over. Zero out both regs. Turn up hpr to about 200psi or so by the guage. Then turn up LPR till the bolt moves back. Shoot it and see what it does. If it shoots but moves slowly but no leak, then give the LPR a quarter turn. That should be where the gun needs it.
Each gun always uses what it needs. To set it off another person's exact numbers is always going to be wrong. Gauges in paintball will always be wrong, unless you are using a certified gauge that has a 1% +/-.
If you are still having a leak, then look at a possible blockage at the air transfer port(the opening is in the LPR threads). Take off the noid and LPR and blow it out(use your breathe) to see if there is something blocking it. If all that and it still does the same thing, send me the LPR at least if not the entire gun sans barrel and i will tech it for you,
