So it looks like HP tuners got ahold of some more TCMs or either has a different method of unlocking them, their website now shows both TCMs in stock but it looks like they are requesting the Serv# on your TCM to tell which one you have. I have to find time to dig into my front end to see if the Serv# is visable without removing anything. Anyone try this yet?
