Run a fuel pressure gauge into the car (not a real good idea for all the time if it leaks, or use a fuel pressure sender and an electric fuel pressure gauge) or hold it ĝut the window.

What you're looking for is when the car goes lean and what the fuel pressure is doing.

Chances are you'll need a rising rate fuel pressure regulator to maintain adequate fuel flow to the injectors if not a larger set of injectors....especially if you're running above 15lbs boost.

Have you checked your F/A meter against a car with a known good running engine?

Are your plugs blistered or white.....just cuz the meter says it's lean doesn't necessarily...
