it can take a few thousand cycles for a spring to settle... I would honestly open it up and separate the piston and piston head, see if there is a spacer inside the piston or a bearing.. take it out.. chrono it, it'll be about 30fps less depending if it's a solid chunk or if it's a bearing you can take 2 or 3 pieces out that will drop around 10 fps per piece. For a bearing assembly, first part you take out is the bearing plate. Leave the spacers.

Chrono it after taking the spacer out, then game it... few months down the line, chrono it again. IF it's dropped 20-30 fps, put your piston assembly back to the way it was and now your gun is under 400.
