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 5 anymore!
These plug-and-play performance chips especially developed for this petrol 550i 408 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.
Instructions for DIY installation should be more detailled and specific for every single car model. Simple things as intake air filter position makes wiring more difficult in my fabia than in volks.
Everything is very explicit, .... commom knowledge. Connectivity very easy and app also no problem. Engine responds very well, no alterations registered for the moment. Sure to be recommended.
Everything is working fine.
I am very satisfied with the TuningBox Fusion, this optimization pack is really prodigious! Serious and very professional company.
Great Service, keep as it is and no improvements needed
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.
