Regarding the exhaust fumes, I think the FN still had the same problem.
Im not a too good pilot, so I used IL2 compare for La-5F and FN speed data, and it shows close to prototype performance for the FN. Turn performance is also corresponds to prototype La-5FN. This is why I think that acceleration is also based on that.
I dont know how accurate IL2 compare is, but one thing is sure, all Lavochkins benefit from using Forsazh at all altitudes, while in reality it could be used only up to ~2700-3000m.

That is the biggest problem with some of the engine boosts. It works well for the types that affected power at all altitudes but not at the ones that had limited altitude applications (except the very specialized GM-1).
The one thing I don't understand about Forsazh is why it has a limit in altitude. Was it something to do with fuel/air mixtures? The way that the supercharger on the engine interacted with higher pressures at altitude? I have no idea.
Also curious... La-5FN prototype... I know it was hand built but how different was it from a stock performance version from middle to late 1944? I was figuring that unless weight was substantially different (i.e. due to inclusion of standard equipment like guns, ammo, radio, etc.) it should be fairly similar to the later models that the game represents. The 1943 tag next to the La-5FN should probably be changed to 1944.
