Reduced turbo lag for everyday driving
Complementary to Stage 1 or Stage 2

The Workshop Toolkit

The tools and equipment we use to deliver this service with precision.

1

Mercedes-Benz EPC Access

We connect directly to the charge pressure control unit via the Mercedes-Benz EPC system to read and rewrite CPC specific mapping tables. This gives us OEM level control over the calibration.

EquipmentAutel Elite with Mercedes-Benz software
2

Boost Solenoid Calibration

We recalibrate the boost control solenoid mapping to reduce turbo lag and increase response across the RPM range. The result is much more linear power delivery.

EquipmentBoost pressure vs. throttle position tables
3

Wastegate Actuator Optimisation

We fine tune wastegate duty cycle to improve spool time and maintain stable boost throughout the power band. This works with the boost solenoid for optimal response.

Common Questions

What is CPC tuning?+

CPC (Charge Pressure Control) tuning adjusts the boost control system on modern Mercedes engines. It works alongside the main ECU tune to deliver more even power delivery and reduced turbo lag.

Do I need CPC tuning with a Stage 1 tune?+

CPC tuning complements our Stage 1 calibration. Combining both delivers the best results as they work together to optimise the entire boost and fuelling strategy.

Which Mercedes engines support CPC tuning?+

We support the M139 (A45, C63, GLA45), M260 (A35, C43), and other modern Mercedes turbo engines. Contact us to confirm your vehicle.

Will it affect my warranty?+

CPC tuning, like any calibration, can be detected by Mercedes dealers. We recommend proceeding outside of the factory warranty period for peace of mind.
