Thanks Skunkmeister. To make clear to everybody, The Fw 190A-8 that were sturmbocks had the GM-1 system installed. Actually if you read carefully the main difference between the Fw 190A-7 and the Fw 190A-8 was the re-design of the fuselage in order to accept an extra tank which was used as a MW50, a GM-1 or (more rarely) an extra fuel tank.In IL-2 neither the MW50 or GM-1 versions are present.The Fw 190A-8 in IL-2 runs in 1.65 ATA because the B4 fuel version is modelled.There is no chance that a Fw 190A-8 Sturmbock was ever used with a B4 fuel AND without a GM-1 system, the way it is modelled in IL-2.So if you want something more than just visual modelling of how sturmbock really was, you should be aware that there is a long way to go.

None of the 190 using the BMW 801D-2 ever used B4 fuel.Only the BMW C-0->C2 used the B4.
So, since the A-3 version, all the 190 flew with C3 fuel.

A higher mannifold pressure was actually obtained with this fuel and slightly changing the compression ration of the BMWC2...and some other changes what gave the D-2 Engine!

Tha maniffold pressure increased through the war just because of the developpement/evolution of the engine, just like in the allied planes happend the same and because of the C3 injection into the compressor to minimize the knocking effect.

The A4 version was build to allow the use of the MW50 but due to production problems of the kits, it never happened, but the A4 fuselage was already ready to accept a 115 Litres fuel tank behind the pilot.

The mw50 was back on rail with the A8 version but it seems none has flew operationaly with it, so it received the fuel tank in the fuselage behind the pilot, but due to the changes of the CoG, the ETC501 was moved 20cm forward to compensate.Some of the A8 had this fuel tank removed and the ETC501 was replaced by an ERLA ETC for a jettisonable fueltank. Those planes were only used as fighter, they hadn't any JABO capacities.
