I am not a technically savvy person. From what I gather, it's possible that my car, a 2014 Mercedes GL450 bi-turbo can be tuned remotely, is that correct? All I am looking to do is increase the idle up to about 1,000 rpm. I am based in the US (Florida). I didn't see any tuners in the US based on the dealer map, is that correct? If so, does anyone know of any shops that offer a remote tune?
Thanks for any help!
