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

Noticeable difference, long term will definitely be worth the money

Having bought a second hand VW Transporter T4 many years ago without the intercooler, I always felt it was a little sluggish. It just needed a bit more get up and go. A friend mentioned Tunit to me and one was soon fitted. What an amazing difference it made. It felt like the engine had been set free. Much more umph which made it easier to drive and about 10% more mpg. The centre that I bought it from were very helpful in getting it set up how I wanted with a little tweek here and there when ever I passed by. It didn't take long before I fitted one to my Skoda Fabia VRS. This was just incredible. It took off like a rocket, had so much more get up and go, more fuel economy - about 12% better and was even more enjoyable to drive. When the good old T4 finally had to go and was replaced by a T5, I knew I'd be OK with the lower hp model because I could add a Tunit to that. Once again there was a total revelation in the power from the new van. At least 10% better fuel economy along with the usual other benefits. When ever I now tow a trailer I just turn up the Tunit to 10 to give me a bit more power, which helps immensely when pulling away with a heavy load up hill. Superb is a good word to describe these units and several of my friends that now have them would agree.
