Firstly, when running nitrous, you don't want to run you 91 tune. Run 91 or 93 fuel, but run the 87 tune, it doesn't advance the spark timing, or you can run the 89 tune and pull 2 degrees for a 100 shot, and you can run up to a 125 shot for short durations, just make sure you pull 4 degrees of timing from the 87 tune.

A set of 1 step colder plugs is highly recommended after a 75 shot.

If you have a Zex kit for a truck then it should come with a piece that will go between your fuel rail and the fuel supply line, this has a 1/8" npt thread in it to screw the -4an fitting into, this then goes to the -4an hose to the fuel in on the control box.

stock fuel pressure is 55-58psi.
