I've been a member here for a while but I've never gotten around to posting, but.... I started lurking on here a short while ago and there's a lot of great material on here. I used to work as a Drivability, Electrical and Heavy Engine Tech for a few shops, was a Certified Master Tech, but slowly grew tired of barely making ends meet. Still wrench in my free time and looking forward to slowly learning more about custom tuning. Thanks to everyone posting up the great material on here!
