XK-R 4.2i V8 Supercharged — J150_S42A Denso — Remap File Stage 2  - Releases

This is a high-performance Stage 2 tuning file for the Jaguar XK-R, powered by the formidable 4.2L Supercharged V8 engine with a Denso ECU. This calibration is designed for vehicles that have been mechanically upgraded with a smaller supercharger pulley and a high-flow sports exhaust system to achieve maximum performance.

This aggressive remap unlocks the full potential of your modified XK-R. We have extensively recalibrated the boost, fueling, and ignition timing maps to take full advantage of the increased airflow from the new hardware. The result is a massive increase in horsepower and torque, delivering exhilarating acceleration and a much more aggressive engine sound, transforming your Jaguar into a true supercar competitor.
