First on the list was to improve the exhaust note of the stifled 5.5l V8 BiTurbo engine. For this job, we imported a Capristo exhaust system from Germany. Capristo is the most exquisite exhaust systems on the market for the E 63 S, featuring a centre silencer delete, two valved rear silencers which are all controlled by a sophisticated valve controller operated on the fly by the supplied key fob or under back-pressure change.

As part of this huge performance upgrade we are installing a performance ECU remap to improve power, torque, drivability and responsiveness, all whilst retaining the factory silky smooth drivability and fuel efficiency.

Regal-Autosport-Mercedes-AMG-E-63-AMG-S-E63-Capristo-Remap-EVOMSit-Exhaust-Tuning-IMG_4615Once the ECU remap is installed we head to the dyno to data log the parameters of interest to ensure the engine is running as intended and perform power sweep tests to find out the power. What’s important here is that with the ECU remap all of the OEM engine protection is retained.

Once the ECU remap is installed the E 63 S produced 632HP & 696TQ. With an intake +150lbfts at 3000RPM and an additional 82HP at 6500RPM the E 63 S has been completely transformed.
