I burn .6 gph at idle with the a/c on in a hot day with the tranny in gear, so I'm now feeling lucky!

Can you back the idle down a bit? I managed to back mine down to ~600 rpms which trimmed down the idle consumption rate to ~.45-.48 gph according to the SG. Before it was about .55 gph. But if i kick on the AC or steer or cause the fan to turn on, the idle jumps up to close to 1k rpms.
