I have a Red Wolf HP in .22 cal. With the G2 board. I would really like to concentrate shooting the 25 grain JSB or FX pellet on medium power. I am wondering if I can improve on the factory settings by purchasing a tuner or are the gun’s settings from the factory about as good as it gets? I am not familiar enough with electronic tuning to know if the gains you might see are worth the price of a tuner. Any advise is greatly appreciated. Thanks
