This has to be the worst company I have ever used in my 65 years on this Earth.. The box I bought for my car was reconditioned but arrived with rust all over outside but never mind I thought as long as it does the job of helping with fuel consumption well it actually had the opposite effect fuel consumption got worse I was told when i was buying it over the phone that if it needed final tweeking there was an agent of theirs 15 miles away so I obviously thought that would be sorted out under the warranty but oh no when I told them about it not working I was told I could take it to their agent but that I would have to pay to get it done so basically the warranty is worthless and the box was not fit for purpose.. I then sent the box back to them last November within the first 30 days and rang up for my refund to be told they would be taking a handling charge off the total when I said you can not do that as the box is faulty and not fit for purpose I got some guff about yes we can because it is a bespoke product so it was left at that they had the box back and still had my money I eventually got a FULL refund towards the end of March this year but only after getting Tradeing standards involved in the case and they sorted it out for me ...., So in my case box not fit for purpose.... Warranty not fit for purpose.... and trying to get a refund a nightmare.... Would i recommend this company ABSOLUTELY NOT...

Fantastic product, very easy to fit and use via phone app, fuel saving greatly improved and noticeable power increase especially at mid range, changing modes using the app easily done.

My 330D BMW Touring was always good on performance but having seen an ad for Tunit specifically citing their unit’s increase in bhp and mpg improvement I spoke to Mark at Tunit who reassured me of the benefits from fitting his unit.
It was expertly installed by UMS in Uckfield and the resulting difference in acceleration is simply breathtaking.
I wasn’t expecting such an improvement from such a straightforward and affordable upgrade Recommended highly.

I inherited a 1998 Vauxhall Frontera Transglobal 2.5 Diesel two years ago. Not my first choice of vehicle! And when I first drove it, my reaction was (modified for print!) "What have I got here? What a gutless heap this car is". Then I fitted a TUNIT to it, and my God, it was like a completely different car. It responded well; it accelerated hard; I got a better MPG. It was a totally different vehicle. This is the third car to which I have fitted A TUNIT, and I can thoroughly recommend it. Money well spent, certainly, because it saves you money, and introduces extremely pleasurable driving.

Wow, what a difference. Brilliant device!!
Van now pulls through all the gears, even up the hills.
Would recommend to anyone

Great products and Rhys was very helpful with an problems that I experienced with my products fully recommend

I needed to but a Tunin Advantage but I didn't know which one, this guy helped me and made the order himself.
