Springer Question Vorteck Tune Kit

Put the Vortek Kit in my 1985 Beeman R1 (HW80) .20 cal. Gun was not used for last 25 years. Did a chrono recently and with Beeman Silver Bear pellets, it was shooting an average of 633 fps with a spread of 616-641 fps. Installed the kit with no problems and the same pellet was shooting 944 fps with a spread of 927-953. Also did a series of tests with the Beeman Crow Magnum pellet. It brought new life into an old gun. I can now hit a beer can at around 50 yards off a rest with no problems.
