Peugeot 308 1.2 e-THP Stage 1 Remap
On Peugeot 308 1.2 e-THP 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. 1.2 e-THP engines with 110–130 bhp reach 145 bhp with a Stage 1 remap; the largest gain is +35 bhp (1.2 e-THP 110hp). 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 turbocharged petrol engine
This vehicle uses a turbocharged petrol engine. On turbo petrols the ECU constantly adjusts boost pressure, ignition timing and mixture based on feedback from the knock sensors.
How a Stage 1 remap works on the Peugeot 308 1.2 e-THP
A Stage 1 remap recalibrates boost targets, ignition and fuel maps together; mid-range torque rises clearly. Knock protection, exhaust temperature and turbo speed limits are kept.
Pre-remap checklist
- Spark plugs and coils; they must not misfire under the higher load.
- Leaks in the boost and intercooler hoses.
- Fuel quality and recommended octane.
- Intake valve carbon build-up on direct-injection engines.
The result depends on fuel quality and service condition; figures are confirmed by measurement.
