The tunit absolutley transforms the car. I was beginning to wish I had bought the 3 litre, but no need now. Brilliant service and product, I will spread the word. I think most people are sceptical of these things, but once tried you become an instant believer, and a very happy one at that. Regards

Thanks for all your help on Monday, I didn?t appreciate the difference in my car until yesterday. Getting into it after not driving for 24 hours was a revelation. Cold starting did not produce the usual black smoke, there was no hesitation when moving off form standstill and the throttle response was much quicker with VERY smooth acceleration. So smooth that my wife commented on it. The improvement to torque at low revs means that the car will trickle along in 3rd gear without throttle, even up a slight incline! All in all Tunit is worth every penny.
