I get dozens of emails a day, I welcome the news and feedback, and read all of it (except the spam of course), but I'm sorry to say, I still can't possibly reply to it all. If you have a question regarding a problem with your car try to send me all the details as so I can point you in the right direction as well as I can.
Did you read the FAQ page?
How about turbo myths, fact vs. fiction?
Did you review Tricks & Tips for going fast?
Did you check out the common problems and mistakes page?
Consider checking out the mailing lists and their searchable archives?
An excellent webboard that handles many questions is www.turbododge.com
I'm currently taking a break due to high e-mail volume.
