The Tuning Box Fusion is the combination of these two chiptuning units. This wonderful product provides an amazing driving experience and great performance. You will not recognize your Bmw Serie 8 anymore!
These plug-and-play performance chips especially developed for this petrol M 850i 530 hp engine work as a custom engine reprogramming. Thanks to the supplied AMP plugs, these chiptuning units can be easily connected and they scrupulously respect the power reserves and motor protection systems of the german manufacturer.
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.
Everything is working fine.
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).
Great Service, keep as it is and no improvements needed
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!
