His name is Lyndon Wester, extremely nice guy. Tell him Michael Mayo sent you.
Tim, you don't have to take it out for warranty work, there is no way for them to detect it. He puts the latest GM updates on the PCMs, so if they look at it they leave it alone. If they happen to update it for any reason, he'll send you a new one and you ship yours back to him.
