F12/F13 M6 & F06 M6 Gran Coupe (2012 - current)
I sold my M6 and so now I am selling the Dinan Stage 1 module and harness.
It was by far the best upgrade I did for the car. Never an issue and major power improvement.
$2400. /OBO. Can be installed directly on M6 or with software update on M5.
PM if interested. Located in SF Bay Area.
