Right now I'm running 8 psi and have my higher MAP values in the timing table set to around 17 degrees under full throttle/boost. Just curious what everyone else is using..

You can't go by what everybody else is using. It is VERY specific to your setup and your environment. You need to tune the spark table to where you get the most power and no knock, its different for everybody. Somebody could come in here and say they are running near 25 advance at full throttle/boost, you go type that number in, and blow your engine up.

Buy stuff from CarCustoms Ebay! Won't be disappointed!

Ron is correct.. This is where strapping it on the Dyno is needed to get the best tune.

Dyno is the way to go like the other guys have said.

To answer your question, I am running 24 degrees of advance and that was dyno tuned.
