Stage 1 software upgrade
Our Stage 1 ECU Remap for the C63 & C63s 4.0T engine gives a significant boost in performance. Engine power increases to around 590 bhp and torque to around 850Nm which transforms the way the car drives. We have tuned many of these engines and spent countless hours developing and testing the software to produce reliable performance every time.
Stage 2 software upgrade
Stage 2 performance figures of around 620 Bhp and 920 Nm are going to impress. Exhaust upgrade and intake for more flow are necessary before we can calibrate the engine ECU to Stage 2 performance levels.
