Known for being the first to introduce a truly potent ECU performance tune and pulley upgrade for the Range Rovers, whether it be the 3.0L, 4.2L, or 5.0L, our packages have been producing consistent and reliable power since the summer of 2009 for Jaguar's 5.0L line up.

By reprogramming the ECU, not only were we able to increase the power of this heavy Rover, we were also able to remove the speed limiter, hesitation/flat spots, and raise the RPM all while improving fuel economy by 10-15%. Stock figures for this supercharged variant is 510hp / 461tq, after the installation of our performance package power jumps up to 618hp / 556tq! Tested on our Superflow Autodyn-880E awd linked dyno.

When it comes to the pulley upgrade, installation is a simple procedure. Thanks to our unique Range Rover pulley puller, designed specifically for the 5.0L, removal of the factory pulley can be completed in as little as 15 minutes with no damage to the pulley itself.

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.
