Which GLC engine gains most?
The petrol turbos deliver the largest outright gains, while the CDI diesels excel at mid-range torque suited to a vehicle of this weight.
Can I disable the AdBlue system?
Not on public roads: regulations require emissions systems to remain operational. Ask us about your specific case before ordering anything.
Is the work reversible?
Yes. We always keep the original ECU file, so the vehicle can be returned to its factory configuration.
