Tuning RWS / Diana 52 T01 - Tunekit

Gentlemen, I just got an D52 T01 from 06 02. I would like to make it as good as it can be, so a tunekit is in order. Vortek and Maccari seem well received, but in this business there is also plenty of opoortunity for scams…So, a few questions:

Is the real Maccari still in business?

which tune would you recommend? ( yes, I would like my D52 to shoot as powerfull as possible with no twang, and shortest cycle, and as smooth as possible - and yes, I assume I cannot have it all, but a good combo would be nice)

Any other recommendations? It is a T01, for which I like the safety, but have read different pros and cons otherwise…

Thank you in advance for help and words of wisdom..
 
Yes, Jim Maccari is very much still in business https://www.airrifleheadquarters.com/page/page/251327.htm

I’ve used both Vortek and ARH kits with great success, but am not familiar enough with the D52 options to give a recommendation. That said, it has generally been my experience that Vortek kits deliver more power with correspondingly more snap and ARH kits are smoother shooting. Also, if you have questions Tom at Vortek is more responsive and will try and help you. Good luck.
