I had my Tunit fitted Wednesday afternoon by Rob Cotterell.....the unit is simply awsome...very very impressive........but what impressed me even more was Rob Cotterell himself.....he was such a nice guy.....explained what he had to do......checked it more than once......explained how it worked .....wired it in ,so i could take it out myself if i ever sell the truck ......and then put it all back so you would never know it was there......totally professional and one of the most genuine mechanics i,ve ever met.

After much deliberation of what performance enhancing product I was goin to use to improve my VW Golf GT TDi I am sure I have opted for the correct decision, greatly improved low end torque and noticeable power gains with fuel economy! I am a happy man! And I am still on setting 5, Thanks Tunit!
