Its a fast aircraft and should be flown that way.
The key to being successful is the fuel loading.
You wont need more than 25%, that's 30-40 mins flying iirc.
If you do, take drop tanks and ditch them at first sign of enemy.
Like most aircraft in IL2 1946 you need to learn their particular weaknesses and strengths.
Changing FM and DM wont stop you getting shot down.
As far as mission building goes use the same tactic with fuel and speed.
I have that same problem with FW's getting killed to easily by Russian counterparts
