Nice gun, I would shoot it as is for a couple of tins before messing with the tune, let it break in sort of speak. Looks like its shooting pretty sweet and the shot count should be fantastic at those velocity's
Reality: high end pcp $1,700.00, decent scope $400.00, mid-range compressor $1,000.00, CF bottle with gauges and fill whip $700.00 and you should be good to go. These are not the highest or the lowest numbers just an average.
I used something like this when I was using a lower priced compressor. I have several higher end guns today, so I broke down and got an Alkin which is used for breathable air.
