Jaguar XF V8 Supercharged Gets ECU Tune by VRTuned - 1,306 views
When this customer contacted me about wanting to get his Jaguar XF Supercharged sedan flashed, I was on board! Such a unique and cool car, the Jaguar XF comes stock with 470 horsepower. Like any forced induction vehicle, it stands very strong to gain big with a ECU Tune. VRTuned did a bench flash on this ECU since OBDII was not an option. On our Mustang Dyno running the car in AWD, we had a ambient temperature of about 100F using 91 octane. This is a cocktail for low reads, but what matter to us was the before and after gains. Naturally cooler temperatures and better fuel will yield higher results.
Being supercharged, its Horsepower and Torque are usually on a perfect match and this was evident with gains of 40awhp and 40ft/lbs of torque at 5300 rpm. The Jaguar gained consistantly from 3000rpm to about 6000rpm. A high flow exhaust and smaller supercharger pulley would be the next step to gaining about 75 wheel horsepower from this cat.
