Does input pressure effect # of shots?

Hello,

I have an Emag, and while using a stock barrel, I get roughly 600 shots per 68 3k tank... keep in mind that it is a preset at 850 psi. Now if had an adjustable tank at 600 psi, will I get more shots or will it be the same?

No. It will only adjust the reactiveness of the trigger if it's in manual or hybrid mode.

If that is the case, then why are my shots so low?... I mean you are suppose to get roughly 950 on the stock barrel right?... What can I do to improve this?
