My Jaguar XJC V12 visits the dyno & the result is more power & it sounds even better!

My Jaguar XJC V12 Coupe now has a new £12,000 fuel injection & ignition system, which was developed and fitted at Tom Lenthall Ltd and is now running better than ever. It sounds even better too, thanks to a new exhaust system, which is better suited to the tuned V12 engine.
