The Tunit II 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 II 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.

Thanks very much for your recent service on my purchase of Tunit for my 406. I must say that the help, assistance and service from all of you has been first class and it has been a pleasure to deal with you. The true test came recently when I towed my caravan and awning to North Devon, where I noticed a vast improvement. Thanks for all your help again

After Installation the D3 vastly improved in performance reving like a petrol engine and the extra torque made it pull much harder through the gears.Also it improved the mpg by 4 which is outstanding.Highly reccomended Thanks Dave
