The Tunit III focuses on reducing the lag seen on older diesel engines. Mid-range improved torque makes driving much more of a pleasure bringing benefits in economy also.
The Tunit III is adjustable on installation. If the vehicle has a change of use then further adjustments can be made.
The Tunit has provided economy for many years on an array of applications and has been used extensively on Military vehicles.

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
