REVIEWS

Martin,Mercedes Sprinter 213 CDI

despite the vans size and 130hp engine whilst overtaking, the van frequently outperform's ordinary cars in acceleration

Haydn,VW Touareg 2.5

The tunit absolutley transforms the car. I was beginning to wish I had bought the 3 litre, but no need now. Brilliant service and product, I will spread the word. I think most people are sceptical of these things, but once tried you become an instant believer, and a very happy one at that. Regards
