Adding our Tune Pedal P13712 (Picture required), on your petrol 523i 177 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.
I am very satisfied with the order process, customer support and i will recommend yo others. Many thanks
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.
all very well
I would like to see an improvement in shipping because it got delayed twice
Great webshop, very good communication, fast shipping, good packaging. But never understood why the Fusion range are only available to some cars - and not mine (2009 Peugeot 407 sw 2.7 hdi).
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.
