Car still won't run well

[alpalwal]

My car is finally running, but poorly. It's a built KA-t with msd 50lb injectors and a safc

first off my boost gauge only says 10" of vac at idle and it should be at 20. I tried the boost leak tester and i didn't find anything. What else could lead to low vacuum?

second, when you try to rev the engine up at all it just dies. i've gotten it up to like 1.5k with like 2% throttle, but any more and it dies.

the safc was all set up for my old sohc ka with 450's. besides leaning the injectors out a bit, is there anything else I should have changed between sohc and dohc?
