Getting ready to run a nitrous system. Have a triple pillar pod and air/fuel ratio gauge. What 2 other gauges should I get? The bottle has a bottle pressure gauge on it. Should I get the one that runs to the front or just work with the one on the bottle? Also take into account I'm using switches to activate a bottle heater and remote bottle opener.

 

uhm...if you really want, fuel pressure (electrical), and get one for the pressure so you can see if pressure is too high...things change with temp. I dunno about the pillar pod though...gets unwanted attention with that many gauges, and points the nitrous gauge right at your head if you place it incorrectly... 1800psi running to it...could be dangerous. try to get it low enough that it wont hit you in the face should anything break.
