Default Idle Issue

I have an A4 with a fairly large cam. The car idles fairly good when it is in park: around 900 rpms. As soon as I put the car into gear, the RPMs drop to about 500 and the car struggles to stay running and usually dies? What would causes this and what tables can I chance to help fix this.

The basics should clear that up. What all have you changed? Try:

Raise Idle RPM
Raise RAF
Lower VE

What timing is commanded in your Base Spark In Gear table for idle? A fairly large cam will require 29~32* of timing for in gear scenarios.

The Base Spark in Gear right now is about 17 to 20*. The motor will be supercharger, but right now it is N/A so that the motor can be broken in. I will try bumping up the timing to see if that helps.
