Fantastic company to deal with. Tunit gives the vehicle more drivability and low down torque great for either towing or carrying heavy cargo. Inturn you get better mpg due to staying in top gear over longer periods. Used them for years wouldn't go anywhere else.
Well, words can't describe it. I think that I said to you that I never expected to change my other Passat and this one was in fact a most unexpected present (some present!!) and I bought the tunit, which makes the car absolutely stunning. It is such a wonderful combination of power, torque and flexibilty; I find it breathtaking - as do all passengers to date. I can hardly wait to see how it performs with the caravan when I set out tomorrow. I will send you a postcard from Provence to let you know what the verdict is, but I know that it will be superb. I have always loved cars, but have never driven anything like this. I just can't thank you enough
