Paul,VW Amarok

I had the Tunit for 2weeks now and what a hell of a difference. Lots more power and extra 2 miles to the gallon. Here are some figures from my VW Amarok Auto. Standard: 27-31MPG. Old Tunit V-CR: 28-33 MPG. New Tunit Advantage 2: 30-35 MPG and improving.

Les,Toyota Hilux 2.4 Auto

Have previously fitted one to our Kubuta m 6060 as it was struggling to drive our Class Rollant 250 rotafeed no drive's it with ease.Just fitted another to our Toyota Hilux Auto which normally returned 28 averaged to the gallon now averaging 38 and more torque to stay in the higher gears hence better fuel economy.Very pleased.
