REVIEWS

Martyn ,Landrover Defender TD5

I run a Defender TD5 in Dubai, which is all city driving or desert sand driving. The Tunit has allowed me to be a boy racer around town and have enough umff to get up the bigger dune, neither of which was possible before the Tunit.

Murray,Toyota Hilux 3.0 D-4D 171BH

Fantastic increase in fuel economy 7miles to the gallon from 24.4 to 31.5 very pleased
