ECU Tuning Group | Jaguar XF/XFR ECU Upgrade

By reprogramming the ECU, not only were we able to increase power for the Jaguar 5.0 Supercharged engines, we were also able to remove the speed limiter, hesitation/flat spots, and raise the RPM all while improving fuel economy by 10-15%.

We can take the 470hp 424lbs tq XF Supercharged and 510hp 461tq XFR Supercharged to: 565hp & 525+lbs tq with just an ECU tune. By replacing the supercharger pulley, total gains of 590hp & 550+lbs tq can be obtained.

For owners who are not accessible to any of our dealers, you are in luck. We are offering a new package where you will be able to reprogram your vehicle through the OBD II port in the comfort of your own home. The process is simple, safe, and easy. Contact us directly for more information.

Please inquire about any Jaguar model.

Contact the sales department for any questions or concerns.

Please obey all traffic laws. ECU Tuning Group does no encourage speeding.
