Delivery speed is slow. More than week and nothing happens. If your process is slow you should give clear indication about that fact in confirmation. Setting expectation level is good idea.
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.
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.
