Mercedes uses a vacuum operated wastgate so they can control boost with the computer. Less vacuum - less boost. The computer does not cut fuel, it cuts boost which in turn cuts fuel through the aneroid valve. Excessive boost does not melt a diesel, excessive fuel does. Low boost rusults in less power in part because the aneroid valve is not opening up enough to let in full fuel flow. At least that is the way it works on a 1995 S-350.
