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.
Totally happy with the whole process of buying. Clear and easy to use web site and a seamless transition to the payment site. Contacted customer service before purchase, quick and clear reply.

Everything is working fine.
