2nd vehicle i have had tunit on and my range rover is a v6 but drives like a v8! Consumption improved from 25 to 30 miles per gallon. Already have recommended it.

Fantastic company to deal with. Tunit gives the vehicle more drivability and low down torque great for either towing or carrying heavy cargo. Inturn you get better mpg due to staying in top gear over longer periods. Used them for years wouldn't go anywhere else.
