I've got the tunit turned up as high as possible as my car is always packed with heavy gear and still performs well. Seems progressively smoother and doesn't have such a bad dead spot at high revs. I shall probably go through tyres more quickly but it's rejuvenated my love of the car and on average the consumption is still better than before but exact figures I'm not sure of.

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.
