Yeah they called me last week and left a message and wanted the device to ship back to them at no cost to me. Called and said I was call 45 or something and said they would call back but I think I missed there call. But I sent the No go Bama tuner back to the seller! It has to be the software, this is the second tuner that didn't work!! So now I am looking for a matching GT coupe, and maybe I might try a Bama tuner again if I don't find another brand that will work before then.
