L.E.D. fps goes up after set

[Sykotic Elite]

Guys, need a little help. My LED fps grows sometimes after setting with the chroney. If it is set at 275 or so, it may go up to 300 or more during a game. It does not do it all the time. Any suggestions?

Check the pressure on it, then make sure you snap ring is set right.
