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

Bruce,Vauxhall/Opel Meriva 1.3 CDTi

Hi Jerome, I purchased a V-CR unit for my Opel Meriva 1.3CDTI direct from you in early April, I have now had the chance to run it for a month and over 1000 miles. In a word "Superb". The little JTD engine has always been flexible and willing but a little down on power, especially on hills. This has now all changed, there is a lot more power at lower revs, the acceleration is better and it's quieter. I have not had a chance to accurately check the consumption but it looks as though I am using less diesel than before.

So a very happy customer.

Kind Regards
