Informing people with the issues about the TSB can work out in a good way. It all depends on how the customer provides this info to the dealer.
Instead of acting like they are stupid for not knowing about it, educate them. We are all human =) Giving them a heads up and helping them find the info will help out the next CF owner down the road with a similar issue.
The dealers have a million vehicles to watch over. Sometimes TSB's get over looked, as most vehicles aren't effected. Typically, the only time a customer is contacted, is if a RECALL has been issued. TSB's are not required, they are just there to provide solutions to some minor, yet frequent issues for the technicians.
As for crossfiretech, we can go on guessing all day what happened. I think he took something personal and gave up. At least that is what it appears to be.
