UPDATE Price dropped to $499/obo will ship.
I have a 2015 320i. Got a new DME for warranty purposes and have an extra DME with Enzo Performance's tune (1350 miles with tune, 6250 overall). New DME goes for about $1299 and Enzo's tune goes for about $1095. Going to trade in the car for a faster one so I have no need for this extra one. The DME can be flashed back to stock if you prefer, or flashed to your preference at Enzo Performance. Local pickups are welcome and shipping cost is included.
