Adding our Tune Pedal P13702, on your petrol 523i 190 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.
Fast delivery, had an initial issue with one of the connections, but 1 phone call and a technical email later all resolved., I have tried racechip previously but I am more impressed with this company.
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!!!
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.
Hi. I tried many times over Xmas/new year to ring and chat with a person to avail. If this company Cannot contact people over this period let us know. I hope thIs product works. ***
Instructions for my vehicle were not accurate for both the Pedal Tune and ECU Tuning Box. Pls check your diagrams for the BMW X5 E70, N63 engine!
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.
