Good Product. I find hard to attached controller somewhere near the dashboard due to lack of double side sticker.
Good communication and double check regarding the motor type of my BMW by TuningBox. Fast delivery of the box. Everything is working fine without any warninglight. Power increase is very noticeable.
Everything is very explicit, .... commom knowledge. Connectivity very easy and app also no problem. Engine responds very well, no alterations registered for the moment. Sure to be recommended.
When I ordered, there was no stock for the particular car I owned. I waited one week for the stock but had to write in to check what was the status. However, I must say the response was good.
am very pleased with the whole process. You have to watch the transport package, the parcel has got into my hands in poor condition TUNE PEDAL outside the box and the bag torn.
