Petrol · Flash via OBD · Figures published for this engine · Remote remap available UK-wide from £199
Is a remap worth it on the Mercedes-Benz Slk R172 2011?
This is one of the stronger candidates for a remap. The factory map leaves a lot on the table and a Stage 1 flash recovers most of it with no hardware.
What each stage needs
| Stage | Power | Torque | Hardware |
|---|---|---|---|
| Standard | 181 bhp | 300 Nm | None |
| Stage 1 | 239 bhp | 412 Nm | Software only |
Risk on this engine: high
- High 32% gain: substantial stress on turbo(s) and fuel system.
- Torque rises by 113 Nm (38%): elevated drivetrain and clutch stress.
- Naturally aspirated: lower mechanical risk. Gains from timing and fuelling optimisation.
How to keep the risk down
- Uprated intercooler strongly recommended.
- Full engine health check required.
- Verify fuel pump condition.
- Inspect clutch condition before tuning.
- Use RON 97+ fuel to maximise timing advance.
- Keep a copy of the original ECU file before flashing.
