Adding our Tune Pedal P13702, on your petrol 520i 156 hp will make your engine responds more spontaneously and more directly. This throttle tuning system optimizes the response time of your engine by eliminating the latency . The result is that the power of your engine is released faster. This way your acceleration is much more direct. This pedal box is ideal to pass vehicles easily.
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.
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.
Great Service, keep as it is and no improvements needed
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!!!
Good Product. I find hard to attached controller somewhere near the dashboard due to lack of double side sticker.
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.
