This will be the final update unless I find a way to alter spool up rate the way I want. Spool up from idle thrust should be slow, BUT once engines are stable above 50% n1 or so, when you push throttles to full, the spool up should be very fast.

I think you are looking at an inherent flaw of that FSX jet engine model. The spool up behavior is sort of reversed unless you run a lot of parameters outside of the sim. However, if there was a magic switch, let us know. I'm a fan of your work.  :)
