Mercedes-Benz GLA 220 CDI Stage 1 Remap
On Mercedes-Benz GLA 220 CDI 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. 220 CDI engines with 163–170 bhp reach 200 bhp with a Stage 1 remap; the largest gain is +37 bhp (X156 220 CDI 163hp). Pick your version in the table below.

Year / chassis: X156 - 2014 - 2016
| Engine | Power | Torque | Gain |
|---|---|---|---|
| Mercedes-Benz GLA 220 CDI 163hp | 163 → 200 bhp | 420 → 490 Nm | +37 bhp |
| Mercedes-Benz GLA 220 CDI 170hp | 170 → 200 bhp | 350 → 420 Nm | +30 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 Mercedes-Benz OM651 2.1 CDI (200 / 220 / 250 CDI, 2008–2018)
The OM651 is the 2.1-litre four-cylinder diesel of the post-2008 C, E, GLK, GLC, ML, Vito and Sprinter, offered from 136 to 204 hp. Most versions are twin-turbocharged and the hardware is largely shared across outputs.
How a Stage 1 remap works on the Mercedes-Benz GLA 220 CDI
Stage 1 recalibrates injection, rail pressure, boost and the torque limiter. The gain is especially clear on the 200 and 220 CDI outputs. A full low-rev torque curve results, matched to the 7G-Tronic or 9G-Tronic gearbox.
Pre-remap checklist
- Injectors and injector seals (Delphi injector issue on early production).
- Timing chain noise and tensioner condition.
- DPF load and, where fitted, the AdBlue system.
- EGR valve and swirl flap mechanism.
