By combining precision servicing with aggressive performance engineering, we’ve transformed this saloon into a razor-sharp weapon delivering a massive 720 HP and 980 NM of torque—proving exactly what happens when a Jaguar is developed with real-world grit rather than just showroom shine.

Your Jaguar XFR, built your way
One of the strongest parts of this project is that it shows a realistic upgrade pathway. The car was not transformed in one random jump. It was developed in stages, starting with preparation work, then moving through performance hardware, calibration, supercharger upgrades, cooling and final tuning.
That gives Jaguar XFR owners a useful guide to what is possible. You may want to begin with sound and response. You may be interested in a tuning package for stronger road performance. Or you may want to discuss a more serious supercharged build with supporting cooling and hardware upgrades.
Whatever the starting point, the right package can be shaped around the car, the driver and the intended use.
Jaguar XFR Tuning
Hardware upgrades only work properly when the calibration is right. On a project like this, the ECU tuning is what ties the whole package together.
The tuning needs to account for the changes in airflow, boost pressure, exhaust flow and intake temperatures. It also needs to shape how the car delivers its power and torque, how the supercharger behaves under load and how the engine responds throughout the rev range.
This is where VIEZU’s tuning knowledge becomes such an important part of the build. The calibration is not treated as a generic file or a quick adjustment. It is developed around the actual vehicle, the fitted hardware and the intended use of the car. That is what helps turn a collection of high-quality parts into one complete, well-balanced performance package.

Upgrade your Jaguar XFR driving experience today
This Jaguar XFR 5.0 V8 project is a strong example of what can be achieved when a performance build is approached properly from start to finish. The car benefited from mechanical preparation, freer-flowing exhaust hardware, supercharger and pulley upgrades, bespoke ECU tuning and improved temperature control.
The finished result is a more capable, more responsive and far more exciting Jaguar XFR, built around a complete package rather than a single upgrade.
Use the contact form below, or give our friendly team a call to discuss your Jaguar XFR upgrade. We would be delighted to take your driving experience to the next level.
