OK, so we are getting some extra air on startup.

Here's my next suggestion.

Run the same fuel pressure tests under the same conditions as in your original post, no engine running to verify the FP is 2.1 as before but this time, also monitor the AAR opening as well during the test. The AAR should close completely after a few minutes.


However, as SkiVT says above, the TTV is supposed to be open during startup in your latest video. I would defer to that given there is no one else who has tested a new TTV.
I can't afford that.
