Hi Reuben, Just a short note to say a big thank you for fitting my Tunit unit yesterday, i haven't driven the car since collecting it from your centre, but it felt more alert and responsive during the brief drive home.

I've tried a few other types (cheaper and more expensive ones) and this is by far the best. I noticed power gain straight away and have already seen 8mpg improvement on the few short trips I've done. It's easy to adjust to try the different settings and find the one that suits you best which gives you more power to accelerate up to motorway speed quickly and then cruise along using less fuel whilst also allowing safer, much quicker, easier overtakes on country roads too Thank you again for the Advatage 2b
