Such a unique and cool car, the Jaguar S-Type R 4.2L V8 supercharged comes stock with 400 horsepower. Like any forced induction vehicle, it stands very strong to gain big with a ECU Tune. The VR Tuned upgrade adds more horsepower and torque over stock. Simple bolt on upgrades such as an exhaust, headers, air filter and intake will make your car that much quicker! The ECU flash can be used with the factory supercharger pulley or a reduced mass pulley for increase of boost. With our Stage 1 calibration, you are able to gain improved performance on the engine. Your car will have much better throttle response no matter what type of transmission you have. Where your car is sluggish off the line, your newly flashed car picks up right away and pulls harder through the mid and top end RPM range. Overall, the driving characteristics are vastly improved while providing you additional benefits that your car craves for.

What are the benefits of VR Tuned?
#1 priority is our customer service to you!
Our tuning is used worldwide. We have powered vehicles of all types.
All ECU tunes can be reverted back to stock if necessary.
With the VR Tuned ECU Flash, basic bolt-on performance parts will not require a retune of your ECU.
Adding parts such as an exhaust, intake, plenum, pulley, will all adjust with the tune.
If you add higher octane fuel, the ECU will adjust accordingly.
We can tune cars worldwide including JDM, EU, Australian, and USA cars for different types of octane or environments.
Other custom enhancements are available if requested and applicable.
We test and dyno tune on our own cars to make sure what you get is safe, reliable, and gives you the results you want!
