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 �ut 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...
