Theoretical question: Could this set up go lean at WOT?

Is it possible for a modified 7M to go lean at WOT with 660cc injectors and Lexus AFM?
Assuming the largest plate intercooler that will fit in the car, hard pipes, 3 " exhaust without cat, professionally ported head, ported exhaust manifold, and rebuilt stock turbo at 18 psi or so, fuel pressure at 45psi, engine management stock ECU only.

For now just a hypothetical question, I'm not asking for troubleshooting advice on my specific setup at this point because I'm haven't done all the checks that I know how to do. I'm asking whether this set up could potentially generate enough airflow to exceed the maximum capacity of the injectors.

well with the stock turbo, even being a 60-1 at 18 psi would stay rich with lex afm and 550 injectors as long as you have the fuel system upgraded as well.

Thanks. That answers that.
