I'm installing a NX EFI kit very soon and want to run a progressive controller with it. Has anyone heard that when running a progressive controller that you have to relocate the jets from the nozzle to the solenoids? I heard something about needing to do this because the controller pulses the solenoids and it will cause an ultra lean condition because of the ammount of nitrous in the line compared to the ammount of fuel. What say you?
