Joe , Toyota Hilux

The Hilux is used to tow machinery and tools to and from jobs every day. These can be up to 30 miles away. A trailer is being towed nearly all the time with either a tonne or so of topsoil or hardcore or a mini-digger in. This is why the large torque gains where so beneficial to me and the company. This extra torque meant that the fully laden trailer could be pulled at far lower revs resulting in huge gains in fuel economy. The extra power when the trailer is taken off from the tunit still impresses me everytime.

Dave, Mercedes E220D

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
