Trying to locate the MPR switch in the cockpit. I see the MPR indication light in the top right of the front dash and it goes on when I use the MPR keyboard command. But I don't see the physical switch.
Anyways, MPR seems to give a nice little boost. Just did a very rough test and gained an extra 25 kts at 2000 ft in a clean config. Probably could of gotten more if I left it on.
