How much does the 4.0 TFSI biturbo take?
It has genuine headroom thanks to twin turbocharging, even from very high factory figures. We still apply conservative margins.
What is the DL501?
It is the dual-clutch transmission ECU. Work on it adjusts shift points and torque limits, and often complements an engine map.
Is the work reversible?
Yes. We always keep the original ECU file, which matters particularly on a car in this segment.
