Just a quick note to say how impressed I am with the Tunit I had fitted to my truck. On your recommendation I had the Tunit fitted at Car Media in Sudbury, Suffolk. All I can say is that they are a great bunch of guys, they are very knowledgeable and couldn't do enough to help. As for the effects of the Tunit, I'm most impressed, it has totally transformed the truck from a bit of a slug to a tyre-smokin' beasty! Since the Tunit has been fitted, I've found I'm getting around a 7% improvement in fuel economy, which equates to an extra 40 miles per tankful. So thank you for a very good product and service.

The honda 1.7 is a good standard car but no guts. With the ever increasing fuel costs i took the plunge and purchase a tunit with a view to reduce costs on fuel. the end result never looked backed. The car has driving characteristics are so much better. Mid range is fantastic. Bigger cars are so surprised.
