Mercedes-Benz SL 65 AMG Stage 1 Remap
On Mercedes-Benz SL 65 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. 65 AMG engines with 612–670 bhp reach 670–740 bhp with a Stage 1 remap; the largest gain is +110 bhp (65 AMG V12 BiTurbo 630hp). Pick your version in the table below.

GP Power ECU applies the software at its workshop in Hukou, Hsinchu, using EcuPrime-developed files; workshops can also order the file directly.
About the high-performance large-displacement petrol engine (V8, V10, V12, W12, AMG, RS)
This group covers the large-displacement, mostly twin-turbo or supercharged petrol engines of Mercedes-AMG, Audi RS/S, Bentley, Porsche, Maserati, McLaren and similar brands. They make high power from the factory and are managed with tight temperature, knock and torque limits.
How a Stage 1 remap works on the Mercedes-Benz SL 65 AMG
A Stage 1 remap looks at torque request, boost pressure, ignition and gearbox torque limits together. Gains are clear on twin-turbo engines; on large naturally aspirated engines the effect of software is more limited. Cooling and gearbox limits are kept.
Pre-remap checklist
- Spark plugs, coils and fuel quality (high octane recommended).
- Cooling system and intercooler efficiency.
- Gearbox torque capacity and oil condition.
- Fault memory and any previous software or hardware changes.
On these engines the result depends heavily on hardware and fuel; figures are confirmed by measurement.
This section is based on GP Power ECU workshop experience; the power and torque figures come from the catalogue measurement above.
