"After much researching of tuning companies, I decided to opt for Viezu and their V-Switch tuning unit. Initially, I didn't know which product would be suitable for me, but the staff answered all my questions, which helped to make it an easy choice. The product is a nice bit of kit with simple instructions. In short, you connect the unit to your car and download its original map to the unit, and then from the unit you upload the file to a PC and send it to Viezu. They then send back two remap files of your choice which you download to the unit, and then reconnect the unit to the car to re-programme the ECU.

Once the ECU is reprogrammed, the device is removed from the car. I opted for the Power and the Eco/Power blend maps. I then programmed my ECU with the Power map which I have had in my car for two days now and what a transformation! The car was good before but it is absolutely amazing now. It has sharp response and just keeps on pulling – a total pleasure to drive. Unbelievably, even in the short space of time since remapping, my MPG is creeping up as well. I would thoroughly recommend Viezu and its products to anyone. My experience was hassle free from start to finish." Mr A., Gloucester.
