The 2.2 L 4-cylinder in the Jaguar XF is a performance diesel — high injection pressure, a variable-geometry or twin turbocharger, and a tight calibration that was set for global emissions targets rather than for what the engine can actually sustain. That's the gap a custom dyno-developed map closes: not more hardware, just a calibration that matches the engine's real capability.
Our dyno-developed map for the Jaguar XF adds an average of 17 kW (19%) at the wheels and 86 Nm (19%) of engine torque. That's the target band we work towards on this engine — meaningful gains you feel every time you pull out to overtake or climb a grade, without pushing the injectors, turbo or transmission anywhere near their limits.
In practical terms, that works out to around 6 fewer tanks of diesel over 40,000 km. At a typical 15,000 km annual mileage, most Jaguar XF owners save roughly 156 L and $187 per year at the pump — purely from improved combustion efficiency at part-throttle, where diesels spend most of their time.
This Jaguar XF variant ran from 2013–2015. The factory calibration changed very little across that production window; we have the original file for each year and always confirm which one matches the car in front of us before we start.
