Not a word about misfiring cylinders. Nor how fuel injections are
"calibrated".

And running rich to reduce vibration (I notice they did not do a dynamic
machine test for vibration), again, puts your engine in the worst possible
condition for fouling, internal pressure, valve damage...

Lycoming FI's are pretty close, but still have a hell of a lot of "slop".
