Chrysler 300C 3.0 CRD Stage 1 Remap
On Chrysler 300C 3.0 CRD diesel engines a Stage 1 remap recalibrates the fuel quantity, injection timing, boost pressure 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. 3.0 CRD engines with 211–218 bhp reach 275 bhp with a Stage 1 remap; the largest gain is +64 bhp (3.0 CRD 211hp). Pick your version in the table below.

| Engine | Power | Torque | Gain |
|---|---|---|---|
| Chrysler 300C 3.0 CRD 211hp | 211 → 275 bhp | 510 → 600 Nm | +64 bhp |
| Chrysler 300C 3.0 CRD 218hp | 218 → 275 bhp | 510 → 600 Nm | +57 bhp |

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 common-rail turbo diesel engine
This vehicle uses a common-rail turbo diesel engine. In this technology fuel is sprayed from a shared high-pressure rail through electronically controlled injectors, and the ECU constantly manages injection quantity, timing and boost pressure.
How a Stage 1 remap works on the Chrysler 300C 3.0 CRD
A Stage 1 remap recalibrates injection quantity, rail pressure, boost pressure and torque limiters together. Torque gains are clear on diesels and pull improves at low and mid revs. Smoke, exhaust temperature and turbo speed limits are kept.
Pre-remap checklist
- Injector condition and leak-off test.
- Leaks in the turbo and boost circuit.
- EGR valve and, on DPF cars, the differential pressure sensor.
- Clutch and dual-mass flywheel; the extra torque can cause slipping.
Catalogue figures assume a healthy engine; diagnosis first, then software.
