[QUOTE="gman1, post: 1212411, member: 783"] I would try a different dealer or someone with IDS. Something just sounds fishy with what they told you. There is no more customer support because the EPA made them stop making tuners that defeat emissions. I wouldnt worry about the H&S tuner. There are very few that eff up. The ones that get the VID corrupted are the ones that cant be returned to stock. After they are flashed to "as built" all is fine again. The trucks that are returned to a stock tune will usually start once with the emissions stuff deleted. And yes you could return your truck to stock and switch tuners. [/QUOTE]
