How much does a supercharged V8 take?
It has genuine headroom, more than a naturally aspirated engine, and responds well to a measured map on standard hardware.
How does it differ from the standard XK?
The XKR is the supercharged high-performance version. Each has its own entry in our catalogue.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
