Just got my wife's B200T reworked. I installed HID with 8000K and reflashed the ECU. A friend of mine, who is a MB Tech did the reflashing last night and wowwwwwww, what a difference. By theory, I have gained 40 more hp at wheel and the flicking of the HID is gone. It is a bit quieter in my opinion, and the car does drive a bit smoother...
