Every since our workings with the Project CLS63, we have had a strong love for this super sedan.  Equally as beautiful, the CLS550 4.7L V8 Bi-Turbo just needs a little more grunt to get it past the stock 402 bhp it comes with.  The VR Tuned ECU Flash is a great way to get your CLS550 to 530 horsepower to the crank for a more exciting drive.  Faster turbo spool, more torque, quicker throttle response, and stronger pull to redline is delivered with the new tuning.  To flash this ECU, its does require it to be removed from the car.  The Bosch MED17.7.1 ECU is bench flash only right now.  However it is very easy to remove with its location right on top of the engine.  In addition to the CLS550, VR Tuned can tune almost all Mercedes turbo engines for maximum power and improved drivability.  Order your Mercedes CLS550 ECU Flash Here.
