This is just an FYI, really. But....
We just, after several days of fiddling, found out why my crew chief's somewhat modded WRX would just 'lay down' at several different RPM's, always the same. Apparently the knock sensor would retard the timing when it "heard" the rear alternator bearing that was going bad 'vibrate' at certain rpm's. New bearing and now the thing runs like stink. It's making good power at 18psi boost with no flat spots now. I'm too far out of the loop on some of the newer technology, I guess...Whoda thunk it?
