REVIEWS

Andy, Landrover Defender TD5 2.5

The Tunit has transformed the feel of my Defender. Quite frankly, brilliant!

Mike, Dodge Nitro 2.8 CRD

Thanks very much got it fitted easily once you had shown me where to plug it. Just done a short school run and WOW was never going to be a fast car due to its power to weight ratio it was woefully underpowered.. It is a big american lump of iron after all. However have wacked the tunit up to 9 and what a difference, it now drives just so much better, I no longer have to floor the throttle to get a response from the automatic box/engine. It is now truely my dream (family 4x4) car.. It now goes as well as it looks. What a truely amazing piece of kit; every diesel engine should have a Tunit ! Thanks again for the phone calls, emails and humouring me.
