REVIEWS

Allan,Skoda

I received my unit back on the 18th and refitted it over the weekend - what a difference. My Skoda is a different car! All “hollow diesel knock” has now disappeared and the engine performs with increased smoothness (pulling smoothly from 30 mph - 1100/1200 rpm in 4th gear!) and noticeably more pulling power through the gears. With the engine electronics now "put back to spec.” by VW after their emissions scandal and the Tunit unit working correctly, I am impressed. Thanks for your help and looking forward to greater enjoyment from my Skoda.

Gives better response and when you get over the fun of having more power everywhere fuel economy is better and the powers there when needed
