E-85, stock pump (non-green);

Looks like the limit is about 220HP (flywheel, safe number).

Pretty sure I'm out of fuel with the cold weather.
As air flow increases, pressure drops. Commanded voltage and such is in line with what it should be. So I'm out of pump I feel.
But could also be the pump going. I'll have to pull it and see what it looks like ...
Don't "think outside the box".
There is no box.
Do it correct, or do it twice.
