Andrew,Ford Ranger 2.5 TD

It is remarkable how much of a power boost the tunit gave my vehicle, when towing it is a delight I don’t know the van is there. I very rarely need to change gear. I have and will continue to recommend Tunit to anyone and everyone I speak to when the opportunity arises. Well impressed with aftersales on every call the service has been excellent. All queries dealt with politely. Staff are very knowledgeable

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