How safe is JB4 on the 2024 X5 40i? Is it something I could run daily without any concern what so ever (say on map 1)? and is it drivable for my wife too? What concerns me is the possibility of long term damage to existing computers and or engine as well as the JB4 unit itself having an error and leaving me on the side of the road or worse yet blowing up the engine due to some freak error. Also how is the reliability long term? Any increase in risk with the module running for 3+years?
If the JB4 drives like stock but feels like the car just has more HP when you lean into the pedal, and is safe, long term, and can still drive slow and smooth like stock when you are just putting around town, then I would be interested.
