Supercharged Fuel problems

First time posting, I have BDs 1071 blower with dual 1050 holleys. We have a magnafuel 500 pump with a bypass to the tank, we installed a magafuel regulator with the boost reference and the car pops and black smokes at the line, fuel pressure is set at 6.5 and at full throttle we get 13 psi of boost which is 19.5. I disconnect the boost reference, set the pressure to 8.5 and it launches, nothing hard, but then runs out of steam, it is looking for more fuel.

We tried to run a return line regualtor with boost reference and cap off the pump, it takes the regulator pressure (6.5) and makes this the line pressure, so now I am really out of fuel.

I have read some people do not run the boost reference but some do. Can help would be helpful.
