REVIEWS

Murray,Toyota Hilux 3.0 D-4D 171BH

Fantastic increase in fuel economy 7miles to the gallon from 24.4 to 31.5 very pleased

Stephen ,Ford Focus 1.8 TDCi

Since fitting the tunit product I noticed smoother response from the engine even though the car was only 6 months old and obviously more power. Power difference showed more on the motorway when overtaking as plenty of power on tap without gear changes. Fuel consumption is good averaging just under 50mpg if i drive softly enough. Very pleased with the product.
