JB4 and BMW Service

Questions/Advice:
Taking my car in for the 30K mile service, should I uninstall the JB4 first or will it matter? Anyone with experience with this and how BMW responds to seeing the tuning on a car under warranty? Thanks.

I think the general consensus would be to not have it in your car

Remove it.

If there is any additional work needed doing they will blame the map or tell you your warrenty is not valid with aftermarket tunning
