Thanks to the supplied AMP plugs, these chiptuning units can be easily connected and they scrupulously respect the power reserves and motor protection systems of the german manufacturer.
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.
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.
Received the package in 5 days. Installed in less then 5 min on a Skoda Octavia 2019 and it`s a clear difference in acceleration and power. Good customer support! I recommend this guys!!!
My dad wanted it so I ordered from Japan. My dad told me that it works perfect and highly recommended. We live in Japan and have Range Rover Velar. Dad said it takes about only 3 mins.
ALL WENT WELL
