Mustang MkIII?

[IvanK]

Thats exactly it the +25Lbs Boost is only available to a lower Full Throttle height than the standard +18Lbs boost At the higher levels performance should be much the same. Give or take a tad depending on Engine Full throttle height ratings.

The Mustang III is simply a B/C with more power at the lower levels and a slightly differrent Supercharger schedule.

The game uses the extra power in the FM though the MAP guage still reflects the lower rating. The MAP guage indications are earmarked for correction in the Mustang III.

What you see in IL2 Compare is close but not exactly what the FM sees.
