Unless there's damage to the trem (f-d up knife edges, fulcrums, or bad saddles), this shouldn't happen if you have it set up right. And if you stretched your strings enough.

If you take out a spring, then there won't be enough tension and your trem will rise.

The key is that spring tension must equal string tension. Get that right and you shouldn't have to re-tune until the next string change.

It's not intonation--intonation doesn't get affected by trem use. The setup guide mentioned above still could be useful.

I don't have an hour to type the whole procedure out for you, but there's a lot of info in the setup guide thread and not all of it is useful.

Find one that includes blocking the trem while you change strings, stretch them, and tune. Before removing the blocks, you'll need to adjust the spring tension so that the trem stays level without changing the tuning. When the spring tension is correct, the guitar will still be 100% in tune before and after you remove the blocks.

It's not rocket science. You just have to learn the right way and use it. There's few good reasons to block a trem (what a waste). If you don't like the tone with the trem, then you should get a hardtail guitar and let someone have your floyd rose who will appreciate it.
