Absoloutly delighted and it is the 3rd Tunit I have had. A brilliant piece of kit giving 34 more BHP according to the dyno

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.
