i know, i'm turning this nitrous board into my own personal chat room but... i read in one of your posts below that you have no pressure gauge, but you do have a bottle heater. how the hell do you know when your bottle pressure is too low or too high? i am still shocked that a bottle pressure gauge doesn't come in the kit. i probably need one, huh? but that would do me no good unless i had a bottle heater to change the pressure. guess i need one of those too. do you have a blowdown tube? is one neccessary?
