Adding our Tune Pedal P13746, on your diesel 55 TDI Mild Hybrid 349 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 TuningBox Fusion, this optimization pack is really prodigious! Serious and very professional company.
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.
You should send a tracking number. I ordered as express and it took 10 days to arrive and i couldnt track it.
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.
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!
