Remember, the hammer spring tension needs to be strong enough to open the poppet valve. The higher the reg setting the more tension is needed. It's a balance.

hi thank you for getting back to me, and yes it came with a factory regulator new, the only problem is we asked huma-air to set it for me at 12 lb which they never, we still don't know if it need's to be sorted out before it goes into the air cylinder, because you're meant to screw it at the top then underneath
thank you

thank you for your help and advise how many turns does the huma regulator need we've been told 2 then 3 we aren't sure tbh if you could give me some advice there please I'd appreciate it

no what happened is I got into the hobby after having an illness I went to the local gun club, after being there a while I asked if I could buy the artemis p15 from him, we've recently found out the spring had been swapped to an even smaller one, i had to give him the rifle at that point because I didn't know how to change the o ring's for it, long story short the rifle was given to him to replace the o ring's all of them had to be done apparentlyhi thank you for getting back to me, and yes it came with a factory regulator new, the only problem is we asked huma-air to set it for me at 12 lb which they never, we still don't know if it need's to be sorted out before it goes into the air cylinder, because you're meant to screw it at the top then underneath
when he had the rifle he said that he had put the rifle to 11.28 energy foot-lbs but we only recently found out that there are o ring's missing screws too short or not there, basically the rifle seems to of been thrown together 
wxxxxxs!! we noticed the spring is so small it's not even the correct size for any of the spring's for the artemis p15, 
I swear talk about having you're pants pulled down or what, but there's you're answer buddy... no. I'm currently looking for a spring and everywhere seems to be sold out lol thank's anyway Upvote 0
hi i need some information if possible please, my rifle is shooting very slow and wondered if you knew how to turn up the power on the spa regulator's? if you know how too I'd really appreciate it
many thanksUpvote 0
hey buddy quick question if you can help please, I did buy a huma regulator but as they never told me how to adjust it because they was supposed too, I given up on that one, but the Chinese regulator for the p15 do you know by any chance which way it need's turning to turn the velocity up? many thanks

ok thank you for your help and advise, we've been told it has to go ati clockwise for the velocity to go up on the Chinese regulator that came with the artemis p15. and was told to adjust it that way because the one that came with the artemis is apparently set up differently to the other's
really not sure I'm still trying to find a video of someone setting it up, thank you Upvote 0

Ive not dealt with the Artemis/SnowPeak internally adjustable regulators. I generally replace the internally adjustable OEM regulators on my guns with a Huma Air regulator first sign of trouble. But that has been FX, RAW, Hartley not Artemis/SnowPeak.sorry that's meant to say anticlockwise
My one SnowPeak is a Max 1 which is externally adjustable.

I recently got the Huma reg w/extra large plenum for my Stoeger Bullshark, essentially same gun as Snowpeak, and I also got the regulator tester. Anyway, according to the tape gauge the reg came set ar 110 bar by the indicator mark on the set screw. There was also a tiny allen screw included that goes into the set screw as a flow restrictor and prevents any debris from entering reg. It's screwed all the way in then is backed out 2 turns. So that's what I did, maybe did 2 1/2 turns.this one buddy and it came with a plenum for the artemis p15. 1.77 cal we haven't got a clue how to fix it, or what the problem is! we've put it in the rifle but we're getting no speed (velocity) really the max is just over 400fps

There was nothing about adjustments to a screw beneath the set screw. There's rebuild videos that may give information about that.
These are advertised as capable of being set to 155 bar. With the regulator tester I found my tape gauge to br slightly off, about 5 bar lower than marks. Counterclockwise increases the reg pressure. As directed, need to turn set screw about 10 bar above desired setting then back down to desired setting when increasing reg pressure. Lowering pressure can be just turned down.
Set mine to 150 bar and then it was just a direct install.
Two other things I did.
1st: I measured the overall reg length before doing anything and wrote that down for a starting point if/when the reg ever needs to be rebuilt.
2nd: I used an engraving tool and transfered the set screw mark to top of screw, and 140, 150 marks to flat face of the reg. Used a dab paint on a toothpick to color the marks, white for set screw, and orange on reg face. (What showed up best.) Now I can make approximate adjustments by those from front of air tube if needed.

hi thank you for getting back to me, I've got a huma regulator but they was supposed to set it up for me as I didn't know how to, and because I don't know what I have to do to adjust it
I got that plus plenum. and now I've tryed to increase the power and instead of going up, yep it went bloody down!! it's so frustrating 
do you know how to by any chance? thank's again, Upvote 0
Just because you've increased the reg pressure doesn't mean you're going to get more power. The hammer has to hit the exhaust valve hard enough to open it. From what I've read you've over powering the hammer.

thank's for letting me know, well i ended up putting the regulator back to where it was originally because the power went down not up
and these are what the fx v2 chronograph are saying. they were shot with the hades 1.77. now I've put the regulator back to where it was originally it's still not giving me the speed that I'd like and what I can get from the other p15. Upvote 0
It looks like you're trying to set up a sub 12 gun for FAC, so there are other factors involved that the manufactures use to limit the power, which is probably why you're having the results you are by trying to up the power by increasing reg pressure.

thank you for that and I actually have an FAC (licence) and I've got everything I need for it but the know how! my other p15 does what I need it to it's just this one my other one is shooting 818.9 fps no problem, it's like I said it's knowing how to.

Wonder if it has the low power valve. Here's link to getting spare parts if needed.https://spares.bagnallandkirkwood.co.uk/spa/spa-p15-air-rifle-spare-parts/

Look up post by our member @JD. He's got the knowledge on Snowpeaks. Also here's link to my YT playlist on Stoger Bullshark disassembly and reassembly since the basically same gun internally according to JD.

So you're in the UK and you have FAC, but you will need to put that particular rifle on your ticket in order to legally modify for FAC power and once done cannot be reversed, if you can prove you have FAC I will give you the info needed, otherwise I would be breaking the law as it just sounds like your trying to up the power on a restricted rifle to me, and nobody on a UK forum will give you that info.
The 818 fps you are showing is only 11.2ftlb with the 7.56 grain pellet you're using and not FAC power?
