Review on ๐ŸŽ๏ธ GZYF Car 9 Drive Mode Electronic Throttle Controller - Boost Performance for BMW 1-7 Series, X1-X6, Mini Copper by Terrance Castle

Revainrating 2 out of 5

When it works it's great, but put my car in emergency mode

Worked great for a couple of weeks then my car suddenly stalled on the Autobahn...2 hours grandma drove home and missed work...removed device and cleared codes and car is fine...don't know if that so is a defective device or the design itself is flawed ... too bad I will have to go back .... If customer service is not available.

EC - fuel economy mode (fuel savings 3%-8%). NOR - normal mode (return to normal control mode). You can change the boost mode at any time.
