So XC60 D5 2013. Engine with 215 hp and 420 Nm (measured 209 and 423). In general, the engine is already cool, but you always want to fully unleash the potential) The result was 245 hp and 505 Nm.
Subjective feelings: as if the engine was replaced. From low revs, the engine has become much more responsive, the throttle response is instantaneous. Driving around the city has become more comfortable, it’s just great!
The gearbox works just as well without complaints. Subjectively, it began to shift at higher revs (probably adaptation to more torque).
A few days later I tried to measure the consumption. The result was an average of -0.5-0.6 liters in the same city driving mode. Not much, but nice)
