The Mercedes-Benz E 63 AMG? 4-MATIC is a vehicle that continues to impress. In stock form, a vehicle rarely feels this good. The factory was able to push out 550hp & 531tq out of the 5.5L BiTurbo engine. The factory did a decent job of achieving these numbers, but we, at AMR Performance?, know that this is just the "top layer of the onion".
Through development, we notice that the vehicle is very close to what the factory claims. The vehicle's power outputs are a steady 557hp and 513tq. A great base line and close to the factory being "true to their word".
After numerous hours of data acquisition, ECU calibrating (tuning) and extensive software development, the AMR Performance Stage 1 ECU Software upgrade produces a steady, stable & consistent 620hp & 735tq. An increase of +70hp & +222tq with no additional modifications. We have seen as high as +90hp & +250tq, but this was only during first startup conditions when the turbocharger's cooling system is at its lowest temperature and not a realistic "day-to-day" driving conditions.
The AMR Performance Stage 2 ECU Software upgrade is designed for vehicles running a turbo back exhaust system which consist of a minimum of a downpipe and mid-pipe. The Stage 2 software upgrades produces +285tq and +120hp over stock. We have seen as high as +150hp but this was only during first startup conditions when the turbocharger's cooling system is at its lowest temperature and not a realistic "day-to-day" driving conditions.
Rather then focus on that peak power "dyno queen", we focus on a powerband that is reliable, steady, stable and constant. Giving your vehicle the power increase during day-to-day driving and having it readily available the moment the throttle is touched.
We wanted to share our ECU Software upgrade power output plots for the Mercedes E63 AMG BiTurbo 4-MATIC (W212).
