Shock Air Pressure Question

I have a 2011 Trek Fuel EX 8. The rear shock is a Fox Float RP-2, specially modified by Trek. The official description is "Fox Float RP-2, "trail tuned" w/Trek DRCV, ProPedal, rebound; 7.25x2.0."

When I attach my shock pump, the pressure initially registers around 200 lbs. But if I twist the pump fitting just a little harder, the pressure jumps up to 250. I've never pumped the shock up that high. The last time I pumped it up, it was around 210, according to the gauge on the pump. The pump is a stock Trek shock pump, which came with the bike.

Am I being stupid, or is something wrong with my shock, or...??

Thanks in advance

Hi, I would first try another/different type of pump, to get a "second opinion". Sometimes the valves on pumps (in general, I mean - nothing against Trek pumps!) are not that great.
