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.
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 working fine.
