RSC Tuning Live Tune ECU Flash for Jaguar XJ 5.0 V8 SC 2018+
RSC's Jaguar XJ 5.0L SC ECU Flash Tune will leave your tires begging for mercy. With more low end torque and razor sharp throttle response an RSC Tuned XJ will feel more like a V8 than a V6 after tuning.
When paired with our 1.5 PSI supercharger pulley you can expect massive gains of over 100 HP at the wheels and 38 lbs-ft of Torque.
Please note that in late 2017 Range Rover changed the network communication protocol for the 3.0 & 5.0 engines to a Flexray system. As a result for some 2017s, and all 2018+ models, we do not currently have a handheld tuning device that will work with your vehicle. Instead, for these vehicles we offer the option of sending our tuning equipment (Laptop & Hardware) to you & we can remotely tune the vehicle for you at your home. This process does not require anything other than an internet connection, a battery tender to maintain the battery, and someone to plug the hardware into the OBD port on the vehicle. We will login to the computer and take care of the rest.
**Custom Tunes available for vehicles with or without 1.5 PSI pulleys
