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

Kevin, VW Transporter 2.0 TDi

This is the second time I have fitted a Tunit to a vehicle and once again was pleased with the results. I was a little disappointed to say the least with my new T6.1 Transporter (2 ltr 200hp) only returning 30mpg at best when driven steadily. A lot of the Journeys were only commutes or 100 mile trips. Following the installation of the new unit, which was a great experience. the mpg increased to 33 with the unit set at mid point -5. I took a 250 mile trip up to the North West from Norfolk and this raised to 36 mpg. Before the return trip I raised the setting to max and was getting just short of 40 mpg for the journey. Back home and the normal routine I'm returning a 35/36 mpg, greatly improved figure and noticing no detrimental effects on how the vehicle drives. Thank You Tunit.
