1) You'd want to look at ignition timing and check for repeated 3 degree drops. There is a how to read logs thread here if you need additional advice on that: http://www.n54tech.com/forums/showthread.php?t=21269

2) Just double tap the map gauge on the front, or select change map from user adjustment.

3) On higher octane some have gotten away with it.
