If I read the post correctly, the OP found the secret for gas mileage higher than MB's specs, better acceleration, and faster speed.
Disconnect battery for 30 minutes, unplug the front O2 sensors, rape cobalt ss. No CEL.
But play safe. Wait until a few more E55 owners confirm the above before doing it to your car.
