Race Chip Ultimate 550
Selling my Race Chip Ultimate tune which came out of my 2015 550i. This is a piggy back style "tune" which simply plugs into the forward wiring harness under the hood. Very simple plug and play with noticeable throttle response and decent gains considering it is a plug and play style rather than a full remap. Comes with both A and B harness. Asking $450 but really just want to sell it so make an offer. Thank you.
