Adding our Tune Pedal P13708, on your petrol 4.2 344 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.
When I ordered, there was no stock for the particular car I owned. I waited one week for the stock but had to write in to check what was the status. However, I must say the response was good.
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.
I am very satisfied with the TuningBox Fusion, this optimization pack is really prodigious! Serious and very professional company.
I am very satisfied with the order process, customer support and i will recommend yo others. Many thanks
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!
Good Product. I find hard to attached controller somewhere near the dashboard due to lack of double side sticker.
