Here are my results taken from my Flight Data script and converted to Excel/OO charts.

I have done the basic Level Speed and Climb tests and extracted some other info.

Level Speed: Anywhere from 80%-90% below historical data.
Climb: 130% to 180% slower to height than Historical data.


Other:
R.O.C.: Falls away form near-historical above 5000 ft. Bad at 15000 ft (about 35% of historical). Excuse my up and down ROC but its clearly wrong.

"Boost": Does not respond to Boost Cutout Override. Two data sets emerge. One is the gauge reading (Manifold Pressure) which never gets above 6.2lbs and another which does not appear in the cockpit is the Boost C# parameter for Boost rather than Manifold Pressure and ranges from 8.8 through 11.1 and back to 8.1. Not clear which is driving performance (if either)

Max Speed at SL achieved at 2650-2670 RPM

Mission zip file Performance.zip attached for anyone wanting to do some tests themselves. I can explain the chart building of you need.
