Default ZL1 factory fuel system limits...

What power have you seen on stock injectors/pump and at what boost, air/fuel A6 or M6 car?

Have one only making a little over 500 rwhp (A6) car at 11.6:1 a/f. 120+% duty cycle, 10.5 psi, fuel pressure data shows falling to 50 psi

Should have tons of room left in this thing yes?

Don't ZL1s put down 490-500whp stock through an M6? I think yours has a problem.

Even Camaro SS's can make 470-490whp with a cam on their stock fuel system.
