Engine bogging down with any swift throttle change

[JustJeff]

I got home last night, got into relax mode, and forgot to upload the video. I did do some reading and found opposing info about timing and turbo rotaries. I read that trailing doesn't matter nearly as much as leading. That some don't even check trailing after setting leading. But then I also read that timing on turbos in general is much more important on turbo and than n/a. I found that in rotary tech of the other forum so it might have been more geared towards stand alone controls.
