The Firestone Coil-Rite Air Helper Springs # F4150 for your 2005 Infiniti QX56 require a minimum of 5psi to prevent damage to the bags. The maximum air pressure should not exceed 35psi or you risk damaging the bags. I find having an onboard compressor like the Air Lift WirelessONE Compressor System # AL25980 will help you dial in your ride quality while you drive. This system includes a wireless remote that will allow you to adjust the suspension while you drive or from outside the vehicle to measure your sag. You will also be able to pair this to your smartphone with the Air Lift app that will also work as a controller.
