Derek ,Landrover Range Rover Sport

The Sport was a different car once the tunit had been fitted,as soon as I left the Tunit premises I could feel the increased power and the acceleration was a lot smoother, completing the Cannonball 8000 run to Zagreb at high speed really showed the difference that the tunit made.

Hi Dan. Did an trip to London last weekend and drove sensibly, when I hit 350 miles where the light would normally come on, I had a quarter of a tank left. I went on to 401miles before the light came on. Great job, still got the power low down and over the moon at the economy. Thanks very much. Cheers, Mike Gregg
