Default 73 corvette lq4 leaning out at wot

Hi first off thanks in advance for the help. Now on to the problem I have an lq4 engine in my 73 corvette. It has an ls1 intake manifold and injectors, 8 an line from the tank into a walboro 255 to a C5 filter regulator then the 8 an continues all the way to the rails. The system has a 6 an return from the filter regulator back to the tank. When the problem first started I assumed it was a clogged filter so I changer it out and it got a little better but it is still leaning out and it is driving me crazy PLEASE HELP
