ECU Tuning Group | Jaguar 5.0 ECU Upgrade
By reprogramming the ECU, not only were we able to increase power for the Jaguar 5.0 Supercharged and non-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%.
With just an ECU tune, we can take the 470hp 424lbs tq XJ/XJL Supercharged to: 530hp 481lbs tq (Add another 25hp and 28lbs tq if you replace the supercharger pulley).
The XJ/XJL Supersport 510hp 461lbs tq engine to: 555hp 505lbs tq with the ECU/Pulley kit.
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.
