Mercedes Benz new V6 Bi-turbo power-plant is a has proven to respond extremely well to tuning. Recently we had the pleasure of testing our C450 tune with Seth from c450amg.com forum. Other ECU tunes and "piggy-back" boxes were tested on the street and dyno to provide an unbiased comparison and product evaluation. Dyno testing was done at Corr Performance in Louisiana on a All Wheel Drive Dyno Dynamics dyno. Peak gains over stock of +50wHp and +100wTq were reported from dyno testing, with greater gains seen in the mid range. The car tested was in unmodified trim running 93 octane premium gasoline. A dynograph of the results can be seen below.
For tuning, the ECU must be removed and sent to OE Tuning for modification.
