Guys,

I've been using Evans Performance Academy training over the summer tuning my 05 GTO. I can't say enough good things about Jeff Evans and his training videos. He covers many operating systems with specific examples on tuning tables and live training videos specific to different control systems and applications. Jeff also has a forum to answer specific questions. If you just starting, you might want to check them out.
