Tunit for Honda S2000

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…

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.

Making a Silk Purse Out of a Sow's Ear!

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.
