Hey Members,

Summer is here! You know what that means, hot summers equal hot deals . We will be offering a performance software promotion to all CLS63 owners.

Below you will find information on our performance software for the CLS63 Platform.

Through careful remapping of the factory ECU and countless hours of testing, Velos Designwerks is pleased to announce the release of its performance software for the M157 AMG 5.5 Liter Biturbo V8 Engine. Producing an astounding 535 hp and 560 lb-ft off of the assembly line, the Velos Designwerks engineering team has been able to increase this powerplant’s output with peak gains of 145HP and 186 lb ft of torque (SAE Corrected).
The Velos Designwerks CLS63 Performance Software involves a remapping of several of the factory’s ECU maps including, but not limited to, the fuel maps, throttle maps, ignition maps, and limiters.
While there are and will be other options available on the market, the Velos Designwerks Custom ECU Tune for the W218 AMG 5.5 Liter V8 Biturbo Engine produces real gains throughout the powerband that one can realistically expect to duplicate on their own.


Peak Horsepower Gain: 145 @4300 rpm (120 hp to the wheels)
Peak Torque Gain: 186 lb-ft @4300 rpm (154 lb-ft to the wheels)
Gains taken from a sample of runs done on the same dyno in 90+ degree conditions

Note – ECU needs to be sent in to Velos to have software upload completed. ECU is located in center of engine bay against firewall. Please see images
