PLEASE:NEED HELP WITH STRAT "FREEFLYTE" BRIDGE

I have an "83 strat elite with a freeflyte bridge. If i change the tension using an allen wrench in the hole on top of the bridge will it change my intonation. This axe sounds, feels, plays, incredible-but setting the intonation is quite a job. I'd love to change the tension, but would hate through the whole intonation ordeal again.

I wish I had better news for you, but I think the only way you can avoid re-adjusting the intonation yourself is to have someone else do it for you. :)
