How much boost increase on each of the different RC modes and maps?

Boost on the BMW DME is not a hard set target. It gets complicated with predicted mass air flow, etc.
Pure stock is roughly 17-18psi depending on atmospheric conditions.
RC on 7 will add 3-4psi to that “roughly “. I’ve never tested any of the lower numbers so I do not know the drop.
