Selling my racechip gts black off of my 2019 base m5. Was used for 1,000 miles. Car performed incredibly with it. Ran 10.8 a t 128.5 in 2800 da. Not a single issue. This was my first time using a piggy and def impressed. Have since flashed my ecu with aftermarket file....selling racechip now, and will add jb4 for making tweaks and logging.
