ECU Tuning Group | Mercedes Benz CL63 AMG Twin Turbo ECU Upgrade

By reprogramming the Engine Control Unit on the Mercedes Benz CL63 Twin Turbo, resulted gains on a hot engine using 91 octane were 100hp & 121lbs tq, bringing total output on a STOCK car to 636hp & 711lbs tq. As always, no physical alterations were made to the vehicle ie. Exhaust, intake headers, etc. Once the vehicle is reprogrammed, exhaust is considerably deeper and louder in 2nd and 3rd gear, power is widely available throughout the rpm band, hesitation and flat spots are smoothed out, and speed limiter is removed. Additional power can be achieved by replacing secondary cats with high flow 200 cell race cats and/or adding an aftermarket exhaust.
