I want to increase the first regulator from 150 to 180.. Do I have to tune the gun again? I don’t want to touch the second reg it’s set to 130 bars.

You would not need to adjust the second reg. What are you intending to address or gain by adding 30 bar to the first reg?

I’m trying to find the best tune for my gun. Also i like to experiment to (learn more how my gun works) I’m shooting nsa 27.5 gr slugs and was wondering what happens if I increase that reg

If you change nothing else on the rifle nothing will change as you are only changing the pressure the 2nd reg is seeing, this has almost zero effect on the shot cycle other than helping ease the working load on the 2nd reg

I agree, but then why is everybody adjusting the first regulator? If you look at the M3 Tunes thread they are all set at a different pressure, along with the second reg.

@Eddy1840
the only reasons you would want to turn the first regulator up are: if you if need to adjust the second regulator up to achieve your desired fps and maintain a 30 bar difference over the second regulator or for a faster shot cycle/refill of the plenum.
However, if the first regulator is much higher than the second regulator you are more likely to see over shoot and or creep on the second regulator. 30-40 bar over the second reg seems to work well for me.

Thanks @icycrosshairs. My 1st Reg is set at 150 and my 2nd Reg at 80 Bar. Is that too much of a difference?
I'm getting some really large ES numbers shooting .177 cal, 10.43 gr. JSB @ 900 fps. (600 mm bbl). Accuracy is good but the spreads are like 30 fps in a single string.
Regulator issue or valve setting maybe? Thanks for your help.
