You can buy xHP if you want to flash your tranny, and an aftermarket tune for the dme/ecu. There is no bmw updates that I am aware of. The maps you can update yourself but you will need to either buy a lifetime key off eBay or use a laptop and decode it yourself. I would just by the key. Map packs can be found on torrent sites or Google.
