With that cam it will probably be around 60-70 kpa at a 775 rpm idle.

I'm surprised the blm is at 165 (full rich) when you're holding it at 1,300 rpm and 50 kpa. I would expect the BJYL tune to be rich in that area with your big cam. Are you sure you have 61 lb/hr injectors? is fuel pressure at least 14 psi?
