Here are a few of the aircraft I am aware of that benefit from burning specific fuel tanks first:
Spitfires (1, 5, 8, 9, 14): When the time comes to burn off either the bottom or top tank, manually burn the top tank first. It helps with roll capability. This is historically accurate, they would burn the top tank first as they climbed for altitude. The Spit16 already has "sooper"-roll capability, so no need to worry about that model, just fly it and land the easy-mode kills.

The F4U's: If the F4U model has a LEFT wing tank, burn that first. It is historically accurate it as well. It helps avoid dipping the left wing too soon in a stall out.
The P47's: Burn the main tank first. That is the fuel tank that will reach out and grab bullets so it leaks.
The P40E: Burn the main tank first, it helps with the directional "wobble".
The 190's, P51B/D, : standard. Let the plane do its thing.
As far as taking DT's and 50% fuel... don't do that. Don't wear girl underwear when you play this sim-game unless you are female.

If you are anyone really thinks that flying in that manner get them more "killz" they are sadly mistaken. If they need that 100th wee bit extra of chance to squeeze through a situation then they should have not been there to begin with.
