Good work,

My turbo engine idles at 55 Kpa and it will pull down to 20 or so Kpa with trailing throttle.

I take it the timing is stable now?

Start adding or subracting fuel in as many bins as you can reach. Once you can get most of the no load area set, then interpolate to allow the power to climb from there and it will soon be time to start putting under some load.
