What it sounds like is that you need to reset your Hpr and LPR. Not a big thing and easy to explain.
Your HPR is the grip hanging down in front of the trigger guard. Your LPR is the little piece sticking out of the front of the marker under the barrel. If you have the type of HPR that has the finger grooves cut in it, you need to unscrew the bottom piece to reveal the adjuster. Before you add air, back that adjuster out until there is no more tension on it. do the same thing with the adjuster on the LPR.
Plug in your air source. Slowly turn the HPR adjuster in to about 225 psi. then, slowly turn the LPR adjuster in until the bolt cocks back on its own. Continue turning the LPR adjuster in until you start hearing a leak above the trigger. Stop and back the LPR out about 1/2 turn. That should give you a good baseline for the Chrono. increase HPR to increase velocity, deacrease to decrease. if you have any other problems, post up either here or at ICD-owners.com
I like old VW's and ICD products.
I am at the pinnacle of mediocrity.
