Description

Tuning file: +92 PS, +172 Nm, VMAX increased

Gearbox tuning recommended, see suggested files here.

NB!
This engine is very sensitive to DPF filling and DPF often does not get regenerated even if it is quite full. If the car is down on power stock and tuned, and especially if there is a very large dip during turbo switchover, then most likely the DPF needs regeneration (in some cases even replacement). Log the DPF backpressure and regenerate the DPF if necessary. The DPF pressure at 4800 RPM with tuned file should be <700 mbar.

See the provided log for expected good values to make target power.
