May we ask FM-2 carries 250lb bomb instead of 100lb and the performace of Engine for high atittude should be better than now ...Wright R-1820-56 "Cyclone" has modified superchager for high atittude working...^^

This is an engine with a two speed, single stage supercharger. Why would you expect great performance at high altitudes?
The point of replacing the P&W Twin Wasp with the Cyclone was to improve the initial climb rate and avoid the complications of the 2 stage supercharger that had teething troubles in the Pacific.
This model was optimized for low & medium altitude work, and it was used primarily off escort carriers doing convoy duty in the Atlantic.
