Can someone tell me if there are tunes available for this gun
-
What do you want out of the gun ?
-
First off thanks for your reply .I would like to get more speed and fpe if that is possible
-
Will Piatt or Chris Alls is who I would contact...... You can pm Chris as he is a member of this forum......

In my opinion those guns are better suited at the designed 115-130ft/lb output especially considering the short barrel on the carbines. What I would suggest is a good trigger job and a tear down and blue print of the rifle to fix any mismatch of the ports that is common from Evanix. Then a good tune for a nice flat 5-7 shots depending on the ft/lbs wanted and air tube capacity.

They still do rather nicely at around 150 fpe and the Sniper version with stronger sidelever should be able to go even higher. You can check my RS2 tuning thread for things to do.

The issue is his short barrel.

Contact Will Piatt.
Korean guns are his specialty. You will be pleased

Hmm, I made 200+ fpe with 20.5" barrel. Carbine has a 16" barrel so it will make about 45 fps less, let's say 50 fps to be fair. That's still enough to throw BBTs at around 870 fps for 185 fpe if fully tuned. So, a mild tune at 150 fpe is still fully doable and that's enough to push JSBs at 950 fps or some light bullets at around 900 fps. A good tune will also give a power curve and reduce air consumption so I see no reason why the power couldn't be upped to usable levels while having the gun apart.

Can it be done? Sure but if I recall you and many other Evanix guys started breaking valve stems when you got to 150ft/lbs +. I know everyone said is was a design flaw but the valves rarely IF EVER fail in stock rifles working inside there designed limits. In my opinion if you want 150+ reliable ft/lbs you just buy a different rifle. I know the new snipers have the better valve without the o-ring but IMO if you tune the gun to work inside the power levels the gun will always work and give consistent results.
I do want to say that I enjoyed your tuning thread and for people who like to tinker and who understand pushing the limits of a platform usually means a lot of broken parts it makes since. But when tuning a rifle for someone who just wants a little more power without the sacrifice of reliability you need to stay well inside the platforms limits. Just look at Will Piatts "power tunes" for the Evanix rifles. From what I've seen he keep the power under 130ft/lbs and I doubt that's due to an inability to make more power but rather an understanding of what making more power for this platform may cost the customer in reliability. Again just my two cents.

There are many cases of those valve stems snapping at stock power levels and even in .22 guns so that's something that should be fixed as part of a tune anyway. What becomes a problem above 150 fpe is the valve seal as it is made of rather poor material and chips easily. Since the valve stem should be swapped anyway the valve seal could also be swapped to one made of better material at the same time. I don't know what Will does to Evanixes when he tunes it but many tuners of other brands (like John Bowkett) swap inferior factory parts to ones made properly as part of their tune.

Guess we'll just have to agree to disagree. I've shot thousands of rounds from the four 357 Evanix guns I've owned and have never once suffered a valve failure. I appreciate the guys who push the limits of a platform to bring out it's weaknesses but I personally prefer working inside the reliable limits. For example this is a shot string from my 357 3D bull pup after a blueprint rebuild and tune. It was easy to shoot, consistent and deadly accurate.
200 bar fill.
1-828fps.
2-835fps.
3-842fps.
4-836fps.
5-832fps.
6-836fps.
7-826fps.
That's how I prefer to tune my Evanix rifles but again different strokes for different folks.

With a bit more tuning you could have a shot string like this, personally I rather take that 14 shots or that 7 shots closer to 900 fps with lower fill pressure:

I prefer to keep things inside %2 ES.

There's 7 shots within 2% in the middle of that string. They just average around 870 fps and start at around 180 bar.
