Why choose VR Tuned?
The Mercedes-Benz C63 is a monster in sheep's clothing. With it's boisterous 4.0L Bi-Turbo V8 engine making 476 horsepower from the factory, 40 horsepower less than the "C63S" variant, Mercedes-Benz certainly left us more room to gain power! With our ECU flash tune, you will find a quicker throttle response, an increased torque, a faster turbo spool, and top end of the power band that pulls very hard to redline. The VR Tuned flash tune upgrade adds more horsepower than stock, even if the motor is bone-stock! Overall, the driving characteristics are vastly improved while providing you additional benefits that your car craves, focusing less on the typical Benz owner, and refocusing on performance driving!
Options!
Vmax Off - This is an increase or reduction of the maximum speed limit.
Race Exhaust - This option is for those running full race exhaust systems. (Cat-Delete Req.)
Pops & Bangs - Pops and bangs (burble tune) is the result of an ignition delay which creates an exhaust detonation when the throttle pedal is released. Caution, this process must only be used on vehicles with a full race exhaust. This may affect long term engine reliability.
**Some options are not available for different software version of the vehicle. We cannot know this until the factory ECU read is uploaded. If a feature is not available that is extra, we will refund you that amount. We do guarantee to provide you with the best possible performance tune.**
