John,Landrover Range Rover

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.

I use Tunit in my 4.5 tonne Motorhome - It improves overall performance without using more fuel - I am very happy with it
