ALL WENT WELL
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.
I am very satisfied with the TuningBox Fusion, this optimization pack is really prodigious! Serious and very professional company.
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.
Good Product. I find hard to attached controller somewhere near the dashboard due to lack of double side sticker.
