RSC Tuning Live Tune ECU Flash for Jaguar XFR & 5.0L SC Motors

RSC Tuning Live Tune ECU Flash for Jaguar XFR 5.0L

RSC's XFR ECU Flash Tune will leave your tires begging for mercy. With more low end torque and razor sharp throttle response an RSC Tuned XFR dominates most cars on the road while enhancing drivability in every way. When paired with our 1.5 PSI supercharger pulley** you can expect massive gains between 45-50HP at the wheels and 65 lbs-ft of Torque.

The RSC tune is installed via the reliable and easy to use Dimsport MyGenius programming tool. The simple portable device makes installation a breeze in your location at a time of your convenience.

**Custom Tunes available for vehicles with or without 1.5PSI pulleys

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. 

For more information on this process or if you have any additional questions please message us using the messenger button on the website (bottom right corner) or email us at sales@rsctuning.com
