loud noise from the engine...

anyone with any thoughts on this is appriciated...
i have been running my turboed prelude for about a months now and have been noticing that its making a much louder knocking noise (all hondas have this knocking noise) then b4 i installed the turbo... i don't have any after market knock sensor on it but the factory knock sensor should work fine i think.. any ideas wat it might be?
second thing..
i have my a/f ratio running rich all the time when i m boosting but when i go off boost and go idle.. its stays mostly at lean and swings back and forth.. but more to the lean side.... m i running too lean?
also.. sometimes during cruise, it stays on rich for spit sec and falls to lean for a while.. (its like it stops bouncing for a sec) it doesn't seem normal.. has anyone have this problem b4? i think im running lean.. but want to see if anyone knows anything or more?
