94 Z28 Supercharged

I am having problems when I put car into gear. Idle's around 900 but when in gear drops to 300-500. I know a lot of that is related to my cam. Looking at my data log I noticed that my spark advance at idle is in the lower 20's but when I shift into gear it drops to 9-12. IAC count is maxed out at 16...
