One way or the other, it seems that if you have an engine tune and BMW sees it (and they more than likely will if they diagnose it), some or all of your engine/driveline/drivetrain warranty will be voided and nothing good will come of that.
Yes, the tune can very well void the warranty on the entire drive train from the engine to the rear axles and everything in between.
