Vortech SHO Tuning kits

I had one in my .177 Pro Sport and found it to be a very nice improvement to the shot cycle. I switched to the 12 ft lb unit and Love it. Never miss the few extra ft lbs and the shot cycle and cocking effort are Fantastic! 

Still an excellent hunter that drops rabbits in their tracks and the same performance on squirrels,be it head or heart/lung shots out past 35 yds.

That said,I think you'll be quite happy with the Vortek SHO kit in your .22 TX.

Hope this helps.

If you are suggesting going to the SHO tuning kit to increase your velocity over the original factory rifle velocity with no tuning kit in it, I don't think you will gain any velocity - will probably lose some. However, it will smooth it out considerably and make it more accurate from my experience. I purchase the higher power kit and in my AA 177 I still only get about 13 ft lbs but is groups amazingly well.
