Okay, I've been approaching nitrous with baby steps. I was at a 1/2-mile event where I ended up running all-motor because I decided to log fuel pressure and saw, without spray, that pump pressure would drop to 51 psi pretty consistently.

So when should I start to worry?

That's around a normal drop for a car with mods in most cases. Anything lower than 45-47PSI and it doesn't immediately recover pressure then I would look at possibly starting to upgrade the pump or get a boost a pump of some sort.

Thanks Chris, guess I'm just a little nervous about pulling fuel from the rail when pressure is falling to begin with. Guess my winter project will involve deciding between a standalone or a new fuel hat..ugh. This is what the fuel pressure does:
