Just wanted to know what pressure the regulator should be set at, my gauge is showing below 40 on warm idle, I've read that it should be around 43PSI?

Did you disconnect the air pipe to the regulator before measuring?

Standard pressure is 43.5psi - 3 bar, sometimes run a little higher to improve atomisation or stretch the capacity.

While idling its around 38psi without reloving the vacum line.

Should I check it with the vacuum line off?

All setup today, took the vacuum hose off and it was showing 40PSI, so I've adjusted it and its now set to 43PSI with the hose off.

Thanks
