Vortec and other tunes

So I am new here and pretty much to air guns all together. I have dropped my R-9 off for a custom tune, but in all fairness I don't know what it consist of or even what to expect when it returns. It seemed to shoot fine although a little boing or thunk or whatever. Is this noise going to go away is the recoil going to be less upon return. I know these are things I should have asked while dropping it off, but didn't and am just sitting here wondering what the benefits will be when I get the rifle back.
 
I'm not a tuner, my guns are still stock. Maybe someday I'll get into that. I'd imagine that a decent tuner would ask what you want from your gun. There are only so many variables to tinker with while the pellet is in the gun. But making them play nicely together is a tricky task for sure. Do you want power? Accuracy? Shot count? Consistent, repeatable results? Many of these results require sacrificing one of the others. 
 
My understanding of (real) spring gun tuning involves disassembly and cleaning, propper (typically light) lube with thick grease on the spring. Also often involves smoothing/polishing the spring ends to allow them to rotate more freely. The cocking and shot cycle should smooth out, and the buzziness (what I refer to as "rattle-twang") should calm down significantly. Tuning kits like the Vortek often include a new spring, and/or a different top hat and spring guide (I believe Vortek uses delrin material for those bits), that are designed to reduce the spring rotational torque, sloppy clearance between spring and piston, as well as "spring wrap." It's funny, I only own low-end guns, and when I tune them they improve significantly. I've seen others say that their hi-end guns also benefit from a tune. Makes me wonder how hard it could really be to build a gun that is "tuned" out of the box? Typically, a gun in need of a tune is usually a lubrication issue (sometimes a lack of, so times an over abundance of). Just know that often the price of a smooth, quiet springer is a slight loss of velocity.

Well said.
