ok guys, im installing my zex nitrous kit today and i was dead set on starting off with a 100 shot but now im a little nervous-details. i dont have a hand held tuner so i cant retard the timing for NOS,yet. problem is im goin to track this saturday and i planned on spraying. i used to have this same kit on my 02' GT however in that car i had the SVT focus fuel pump and i ran a 100 shot without a tune or timing retard but it was a low mileage car. now with my current stang, its a factory pump car, and has higher mileage. i have however completely gone thru the car and everything has been replaced as far as maintainence goes. i just dont want this car to blow up lol. so what do you all think? I was thinking 100 shot all day long until i get my tuner then i wanted to go to 125 pill. now im like ehh, maybe 75 shot. like i said the car has new tr6 plugs, new fuel filter ect and it run excellent. its just im nervous not being able to take a few degrees out might hurt the motor. but ive run 100 shot before many times with no worries. and ive read in mm&ff that they've run 100 shot without a tune on a stock 2v with no problems. so guys, tell me to stop being a pu$$y and just run the 100 shot so i can feel better and confident about it. or tell me what you all would do, i plan on programming the window switch to spray from 3000-5700. thanks for the advice in advance, oh and i tried the search feature and i went back to beginning of april and nothing, so.....
