smaller fuel injectors means more fuel?

[Ger-Fire]

I have tuned my Lt1, the programmer guy told me that my system was running a little lean, so, he let it know to the pcm that i was running a smaller fuel injertor size, this way, the pcm will inject a little more gas.

is that true?

I have full SLP exhaust system, CAI, 160 degree stat,iridium spark plug,wires.

thanks in advance-

in short,yes.
if you tell the pcm the injector is smaller than it really is,it will send a longer pulswidth.

thats cool to know

yes tricking the pcm into raising the pulse width will work but fuel injectors are not rated for a %100 duty cycle I belive its more like %30 in a nut shell yes a fuel injector can supply more fuel than rated for with higher fuel press and a longer pulse width butthis will reduce the life of your injectors by how much depends on how far you push it

your car will also get more air than what the PCM thinks, if you port the MAF.

I don't know if I would ever mess with the MAF, those things are good to support close to 500hp anyways. And if you screw up, you'll have to get another one anyways.
