also you can buy a cheap copy MPPS cable and do the remote teapot map yourself, it works on most cars anyway so it isn't a waste of money... and handy because you will have the oem file and the teapot mapped file both as a backup... all you need is a laptop and the cable, as it comes with MPPS software just try and buy the latest version available at the lowest price on eBay/amazon or aliexpress.
