Some games are very strict on the max 400fps limit, others aren't so much.
If someone's going to charge you $15 to swap out your spring...go for it.
and some games treat it on a case by case basis depending on your rep in the community (how safe you are, knowledgable, etc).
I may say yes to one guy shooting 405fps at SOME games based on numerous factors, but in the end it comes down to how much I trust that he/she will be safe with the slightly higher fps...usually it is a NO though and go borrow a gun.
