Fuel Question if i were to install #30 injectors (not SVO), jsut #30 would i need custom tuning or a MAFT or would the PCM adjust to the new injectors since they can add or subtraact 25% fuel?

Re: Fuel Question NOS, ive never done custom programming but i can tell you this, pcm will see extra fuel of new injectors and will adjust pulse width accordingly,except at wot when you will flow extra fuel because pulse width is set, not adjustable. <img src="graemlins/gr_barf.gif" border="0" alt="[barf]" />

Re: Fuel Question NOS, my Z is mostly stock, my comments are from my understanding of the closed loop system GM uses. I am GM tech, but am a total performance gear head. Here is some more info i hope is usefull for you; I dont know your mods, but factory programing is for around 350 hp.(gross)
AS you modify the motor you help it move more air,efficient engines use less fuel to make more power. SO this means the power can go up a decent amount on the stock amount of fuel. I am not telling you what to do with nitrous, but make sure you need bigger injectors before you use them. To answer your quest. no you wouldnt foul plugs but you could lose power!
