Default Timing for boost

I got tunerpro for my LT1 and I wanted to know where should I start off for my timing? I am running 5 lbs of boost at 91 oct. and need to know what is a good amount of retard to start off with. Thanks.

Need to update it. I had the engine rebuilt a couple 1000 miles ago. It has dished hypereutectic pistons with a CR of 8.5 I believe. I need to ask my engine builder again.
