Subjects like CEL codes/fixes, turbo timers, BOVs, cold air intakes, modification paths, and manual boost controllers (and more) are all covered there. The long time members don't want to keep answering the same questions over and over, so we ask that you check the FAQs before you ask, and try doing a forum keyword search on the topic.
A couple good places to research are NASICO.com or scoobymods.com. If you google or check those two places and have troble finding info or anything please feel free to search here, or ask. This is a great place to be to learn about your car. Its not the biggest forum, but I have learned almost everything I know about my car here on this forum solely.
