ok im running a 75 right now and it moves, but now i want to be even faster, so i want to move up to a 100 and i have the spark plugs, i heard i dont need a new fuel pump. i heard i can run a 100 on a stock z. can you guys tell me if its ok. ooh and is it ok to spray 1st gear as long as im over 3k rpm, cause damn it hits hard and i get traction. i love it, but i dont want to hurt my motor

 

What system do you have? Im thinking about a 75 shot for my car. just want it to move. Most the time im stuck in traffic doing 50 or less. i am think that Nos is better for me then FI

 

100 shot is fine
