I got some input from Mike one of the owners of e-Racing Sports:

- The e-RAM can be used in conjunction with a wet Nitrous system as long as
the nitrous is not passing through the e-RAM unit on its way to the engine.
The e-RAM must not be activated manually... EVER.

- The e-RAM is designed to activate automatically anytime you floor the gas
pedal. This way, the driver never has to think about it. It just happens
whenever you floor it. Think if the e-RAM as an "always armed" nitrous
system.

- Adding the e-RAM to Nitrous just provides a 7% increase in air - density ON
TOP of whatever that density is at the time of activation - if the "20 shot"
nitrous has also been activated at the same time, then the Super e-RAM will add the 1.7 psi pressure ON TOP of the 14% increase in air-density caused by the nitrous system.
This answers my question.
