PCP's Adjusting vs Tuning?

[phil0352]

My question is do all new guns need to be tuned? If so how easy can you do it yourself or should it be taken to a smith?

Because PCPs have either the fill pressure or the regulator pressure + the hammer blow on the valve to adjust and get to work together, I think what we should do is tune our rifles. Not think about adjusting one parameter independent of the other. The transfer port is another variable and it does affect the regulator performance so maybe it's more like 3. In a inter-related system like this, I think the best way to adjust is to tune. Don't just tweak something, take the time to adjust the other parameters too to get the system working well. It always bugs me a little to hear people talk about changing hammer spring tension to adjust velocity. I'm sure it can be done and on my unregulated Prod I do it too. But on a regulated gun I think the regulator is the coarse or big adjustment for velocity and the hammer spring needs to be changed when the regulator is changed to find it's new sweet spot.

I will continue to enjoy the perfect performance of my untunable Revere. I had more than enough tuning with my LW Synrod.

I like hitting my targets more than experimenting with cooking.

No they don't and depends on the gun.

Just to add to the confusion of the airgun vernacular, we have the process of detuning a break-barrel. I have never equated a process that typically increases accuracy and precision, improves the smoothness of the shot cycle, and increases the enjoyment of a rifle with detuning, simply because it involves a reduction in FPS.

I understand that this thread is about PCP in particular, I just wanted to point out that PCPs do not have a monopoly on interesting word choices.

They certainly don’t. They can’t diesel.

There are lots of discussions about tuning your gun but what does that really mean? Would "adjusting" be a better word to use in some cases do you think? You tune a piano of course because it plays a tune and assume the term "tuning" originates from the idea of piano tuners which is an actual job of course.

With PCP air rifles it seems that tuning would be more related to adding after market parts to allow the rifle to do something other than what the built in adjustments allow it to do. In spring guns tuning almost always refers to after market springs and guides to make it shoot smoother or with more power. With PCP's what is the consensus here of the difference (if there is one) of adjusting vs tuning?

Adjusting is what you do to change the way the gun behaves.

Tuning is making smart adjustments to make the gun behave better.

Tuning most idiots shouldn't do or try after watching there favorite YouTuber and think they have a fundamental knowledge of the mechanically what's going on and how the process works in each stage. Adjustments is different because most gun manuals come with basic how to with bare minum requirements needed.
If you have the equipment to tune and a ear to hear and able to understand what each function is doing then tuning all the way to make your gun into a performances beauty!!
Just my opinion!!!
