Pic of a NOS dry system.

Here the neccessary fuel compensation regulator designed by NOS to ensure that the system will not run lean has been brilliantly disabled.

The pressure line on the NOS provided regulator(blue object between the 2 solenoids ) that Tees into the stock FPR vacuum line has peen plugged(bolt with clamp in the middle of the blue NOS regulator).

This will ensure that your engine will not get the neccessary fuel it needs when nitrous is introduced into the engine.

Don't install you NOS dry kit in this manner.
