Tomorrow's the day when I will finally be able to test my TX200, .22 cal over the chronograph. Over the weekend I installed a Vortek PG4 Tune kit. The temperature tomorrow will range in the low 70's here in the So. Cal. High Desert. I'm interested in hearing from those of you with this tune in a TX200. A month or so ago this rifle was shooting in the range of 630 fps, a year or so ago 740 fps. I realize that these first few outings may not be optimized numbers, but what should I expect with this tune on this rifle? Your help is appreciated. Thanks, Orv.
