I fitted the Tunit as soon as I got it (on time as promised) I then headed off on my scheduled trip to Wales. I notice immediate improvements to smoothness and engine sound. It has changed many detailed driving changes to many to identify at this time but two stand out: Several times I thought I was in forth when I was in sixth due to improved torque and an approx 10% gain in fuel economy but that is only one trip and less than a tank of fuel. Thanx for your help.

"I was recently fortunate to receive a telephone call from the Managing Director of Tunit to inform me that I was the winner of a competition they had placed on Facebook. Forever the sceptic, my initial response was that of disbelief, swiftly followed by "ok, I suppose you want my credit card details now, hahaha!" etc. Fortunately, Michael convinced me that I was indeed the winner, and all that was required was that I attend their HQ at Chorley to have the unit fitted to a car of my choice. Forever the gentleman, I decided to have the upgrade on my wifes 70k Fabia vRS 130. So, on an unseasonably cold and (very) windy day i headed along the M1 and M62 to my appointment. The journey, at normal motorway speeds, but with severe side and headwinds, showed on the OBC that I had achieved around 60mpg, which I was very satisfield with; indeed, I wondered how Tunit could fulfil their claims that I would see improved mpg figures after fitment. Upon arrival, I was warmly met by Lisa and Dan (who was to conduct the before-and-after rolling road sessions, and who would fit the unti), and also joined by Michael, the MD. The first order of business was for the Fabia to be put on the rolling road; for those of you who have never seen their own car put on a rolling road, it is a very loud event and not for the faint-hearted! Dan predicted that the engine, in standard form, would probably be near the 150bhp mark, rather than the 130bhp VAG claim; and the rolling road revealed he was absolutley spot on. The Tunit unit was then fitted, and a further rolling road session undertaken; with the unit on the middle setting, the engine produced 176bhp. Yes, thats correct, 176bhp. A test drive came next, accompanied by Dan. Without wishing to wax lyrical, (and may I say I'm not on the payroll of Tunit) the on-road performance is totally transformed; overtaking manoeuvres are completed in a blink of an eye, in-gear acceleration is amazing, and the need to chang
