Mercedes-Benz SL 63 AMG Stage 1 Remap
On Mercedes-Benz SL 63 AMG turbo petrol engines a Stage 1 remap recalibrates the boost pressure, ignition timing, fuelling and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.
It depends on the generation and the stock output. 63 AMG engines with 525–585 bhp reach 540–660 bhp with a Stage 1 remap; the largest gain is +123 bhp (R231 63 AMG V8 BiTurbo 537hp). Pick your version in the table below.

About the Mercedes-AMG 63 (M156 6.2 naturally aspirated, M157 / M177 / M178 5.5 and 4.0 biturbo)
The AMG 63 engines power the C63, E63, S63, CLS63, G63, GLE63 and AMG GT. The 6.2-litre naturally aspirated M156 (2006–2014) was followed by the 5.5 biturbo M157 and the 4.0 biturbo M177 / M178. They leave the factory with a clear reserve and respond strongly to software.
How a Stage 1 remap works on the Mercedes-Benz SL 63 AMG
On the naturally aspirated M156, Stage 1 re-tunes ignition, fuelling and throttle maps; the gain is measured but throttle response sharpens noticeably. On the biturbo M157 and M177 boost pressure enters the calibration and the torque gain is very clear across the rev range. The MCT / 9G gearbox torque capacity is respected.
Pre-remap checklist
- Camshaft and lifter wear and head bolts on the M156 (known issues).
- Ignition coils, spark plugs and high-pressure fuel pump on the M157 / M177.
- Boost leaks and the intercooler cooling circuit.
- High-octane fuel; the calibration assumes it.
