I dont know buddy from adam. I had a problem getting my truck to accept a download, someone told me to pm him so i did. He replied back and gave me his number to call. I called him told him the problem he told me his best guess to fix it and that was that. My truck accepted it before he pm'd me back, but it was the weekend. Super nice guy and seems to know what he is talking about. No other problems since, i have owned it for a year and half now. Love the low end power.
