how big of a shot?
 

I recently installed a nitrous kit on my ride, and I've had it jetted for 50 since I put it in. It's pretty damn pronounced when I hit it, but I was wondering if I could safely do more. I put new NGK's in it when I installed the system, and when I pulled one out today to see how it's looking, it still looks new. I've gone through two bottles now, and I have some 60 and 75 jets here. Should I run one? And by the way, the system is wet. It's pieced together from a few different parts (NOS cheater solenoids, NX pressure guage, NX shark nozzle, the lines are generic, the bottle is NOS, and the warmer is NX). I think I'm going to throw the 60 in, but I would like some input first. Thanks.

guess no one knows

make sure all vacum lines are not leaking ( brand new ones would be the best ), make sure you are getting enough fuel to the engine ( upgraded pump, injectors )

Yes...I have a few Suggestions...Firstly You should think about running that NX Booster which is supposed to help when running a larger shot..you can find it here

Also..Go for 2 range cooler spark plugs...if you plan to do a 75 shot (Wet of Course!!)...Other than that..you should be fine!!
