Also, they may not void the warranty on the spot when they see something tune related, but when there is some big warranty claim submitted and BMW NA wants a better explanation as to WHY for example a transmission needs to be replaced on a 20k 335i, and usual answer is due to it being modified beyond the stock specifications which in case the claim will be denied.

Maybe something like the fuel pump, misfires.. small things will fly with a tune but the big stuff definitely not.
