My local ducati shop has told me they'll need to hook up their dynometer and remap the chip in my '01 900Sie after I put on my Termignoni slipons. One person on this forum already told me that he hadn't heard of the need for that before. Another person wrote that the chip's CO needs to be changed by 5%. Is it necessary? If so, is it unwise to ride for very long without having it done??
