John,Honda S2000 2.0i

Fantastic product, very easy to fit and use via phone app, fuel saving greatly improved and noticeable power increase especially at mid range, changing modes using the app easily done.

Lee,Mitsubishi L200 2.5 TD

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.
