Injector power gain with NA?

Mino

Hey guys, I have had my Z for about 3 months now and I'm ready to start modding it I did a baseline and the car put down about 253whp stock I was told that the dyno I used read 12% lower then DynoJet. So I'm right on the 280 mark, love this car more and more every time I drive it. Here is my plan for the car I will be doing a lot of track events next year

1. 25 row oil cooler
2. 3" single exit exhaust
3. test pipes with a ebay Y-pipe
4. Stillen Gen3
5. Dyno tune
6.

Number 6 I'm thinking about doing bigger injectors but I don't plan on FI any time soon. I don't know if I will gain any power from it that's why I wanted to ask here with a tune and those mods, the injectors will they give me power? I was also thinking about doing pulleys too. Just wanted to make a bit more then 300+whp the more the better

Thank you guys.
