I was okay with lower spring just because of I do plan on playing indoor games, and that one has a rule of 330 max low.

I don't want to open the gearbox since I don't know anything about it. And it's a CA P90 so changing the spring would require opening the gearbox. (of course someone could scam me cause I don't know the internals)
There's no way there's a M120 spring in that gun shooting 280, unless there's some significant airseal problems or other issues.

A PB chronie is ok in a pinch but a proper airsoft one will be more accurate.

The P90 uses a v6 mechbox, which honestly is one of the easiest mechboxes to work on in existence. It's also really easy to get the mechbox out of a P90. Worth giving it a try, as long as you take your time, watch some vids, etc.
