You've got alot of variables intake and exhaust wise.You really need to check the A/F ratio with the SLP Maf . That's my input, and that's for N/A. If you're going to spray look at the fuel pump and injector rate.

I'm was 430/430rwhp before my fast 90/90 install. My 28.8's were working at a little over 100%. Take it for what it's worth. I've also "heard" stock injectors are good to 460rwhp, but when it starts to take away from performance(about 400rwhp) it's time to upgrade. Just keep your eyes open and get a something in the range of an SVO30. I don't think you'll need anything higher than 38lbs right now. The SVO's will flow around 36-38 on our fuel pressure system

I have no idea which injectors to get. I'm looking at about 450rwhp in the next 6 months.

30-32# will be fine. Stock pump and injectors run out at about 400-430 rwhp all cars are a little different some less some more.
