This is inaccurate. A tune will not void your warranty. Legally, BMW can only deny specific warranty claims IF you have a problem AND they can pin it on the tune (blown charge pipe, prematurely warn valve springs, etc.).
That said, MPPK for me. I just don't think a piggy-back is sophisticated enough to be slapped on to our Bosche DMEs.
