    Did you try the air calc mode patch? This issue is documented fairly well...or the issue it appears to be anyway. You may need to request support to add the patch option for your OS.

    That's great that worked out for you, but I'm currently running mixed and still get the odd dip.

    Ah well, it'll work itself out or it won't. It's beyond my abilities to sus out the culprit behind the problem.

    Thanks for the reply!

    I've not had that patch fix it for me.

    I do almost everything in SD. I see it often. adjusting RPM MAP boundaries seems to help but ultimately will still be there.

    2 Bar OS's will also fix it

    I have not tried that. What is that/where can I find it?

    Not all OSes have it, yours doesn't. When available it's in the Operating System tab/section.
