I liked Tunit because it could be removed due to my new Mercedes being on lease, I have used Tunit before but the performance was a vast improvement on my last experience
Jonathan - August 2017
despite only driving it for a couple of days that initial lag has disappeared
Allan - September 2017
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.
