I have a Vanguard Creed AR-V, it shoots abnormally loud, it sounded like a cannon, everyone around the paintball site now call me the dude with a mini cannon. I have had a 140 pod through it on about a 1k fill 3k air bottle,so about a pod per 500 psi, when it reaches about 500 psi, it started shooting low as expected like other air tank. I'm not too sure if this is normal.
As mentioned, your regs look like they are unballanced and or need servicing.
What is your dwell set to?
I believe there may be a mis-print on that manual...
The way I understand it, adjusting the LPR changes the pressure through the solenoid, how hard the rammer hits the valve, fine tuning with the HPR will adjust the air pressure behind the ball with more control, therefore the velocity.
Perhaps
@foot could shed some light here ?
Because of the nature of the HPR theres only a small amount of adjustment before the reg becomes unbalanced.
Rule of thumb is to set the HPR 1-1.5 turns out from flush, then dial in via the LPR until the correct fps is achieved.
Most HPR errors are made when the unit isnt correctly set prior to installation.
If you take the HPR core out and screw in the adjuster screw all the way you will see the shim stack core rise, if you now install the core into the gun it will effect how the regs ballance and creat issues.
With the core out you should wind the adjuster in untill the shim stack core rises and is FLUSH with the core body, then install.
I have a creed; and have always setup as per the manual (i.e. adjusting the LPR for fine tuning the velocity); work's on mine. In fact I have never adjusted the HPR other than the 1 full turn out. So I'm interested in foot's opinion too.
As to OP's question, mine runs pretty quiet so I hope someone else can shed some light on your particular problem; if it ins't a tuning/balance issue
I would say you are doing everything correctly, You can up your dwell and lower your LPR for a smoother shot too, you will trade off with so efficency but nothing major.
