Fuel Injector Duty Cycle, EFI Live please help. My friend just finished putting an ATI blower on his 2001 5.3 truck and I'm helping him tune it for the blower. I would have thought that the stock injectors would be enough for 5psi, but according to the PID for injector duty cycle I created in EFI Live, they are at like 120% at 4000rpm. That just does not make any sense to me. The formula I used was rpm*inj pulsewidth/1200. Does that sound right?
