are my injectors big enough?
are my injectors big enough? I have a 1993 m6 TA and am currently running 24# svo's. As far as mods all i have is in my sig. I just feel like my power is going flat at higher rpm's. It got a new pump and filter too. My tune is from ion at madz28, but runs like **** untill its warm. As soon as it is warm it runs good, but just doesent feel like its all there.
edit: I do have 3.23's too, but I still dont feel much of a gain over stock, and i did all the mods at once.

you should be fine...svo injectors actually flow more than their rating i believe because they are rated at 39 psi. how high are you revving it? it may just be running out of power stock heads and cam only makes power to 5800 or so
Your injectors are fine. Read my sig and all the mods I have...even after my cam install when I will be running around 450-475, my stock injectors will still be enough, so yours will be perfectly fine. Make sure you dont have a misfire as well. I has a mis, and it caused me to lose power at high RPM's...I couldnt feel it at the low ones though

Have you verified your fuel pressue at WOT under load?
I would trouble shoot the usual culprits: plugs, wires, coil, o2's, opti, etc.

With 450-475rwhp, you need larger injectors, SVO 36# injectors should do you fine.
Well I put in some tr55's with the injectors gapped at .050 so theyr good, I also have msd wires and new msd cap & rotor too. I shift right at 5800. I'm just stumped, shouldent i feel a big difference with cai, lt's and a tune? How much hp is my stock catback holding up?

You have 3.23's but your T56 is geared differently, since it's a '93, so it shouldn't be an issue AFAIK.

I havent verified under load, but it is a new pump, i will verify that though. Plugs, wires, are new, o2's are newer and are delco's, but i used them for awhile when i had some leaky injectors, i would think theyr fine though. I could throw a coil on it i guess, and the opti is stock with 106k on it and a new msd cap & rotor so who knows lol.

Verdad Gallardo Yeah it's the m29, so its like 3.42's for a later model t56. The only thing i did that would hinder performance is the 17x9 ws6 wheels, but that would only set me back a few rwhp. I may have to go to the local speed shop and throw it on the dyno, maby that could tell me something.
I also forgot to say that it feels like the power is coming and going at mid throttle, more so when its cold so its no big deal, but it is really annoying. I talked to the local speed shop (RMCR) They really know their **** and the guy i talk to is an lt1 pro (drives a 383 stroked, blown, lt1 with 800rwhp with no spray). He said it is most likely the tune not being done right for warmup.

Everyone and their mother kept assuring me that stock was more than enough......what difference will I get with my setup if I install SVO 30's, or SVO 36's over my stock injectors??
, stupid foreign cars. And its 85 freakin bucks for adyno run at rmcr. I guess ill just have to do it. 
and do the calculation yourself... I actually have an ethos, but my bro left it in a customer's convertable eclipse and it literally was sitting in a puddle of rainwater in the morning....the top was up too , stupid foreign cars. And its 85 freakin bucks for adyno run at rmcr. I guess ill just have to do it.

As far as injector size 450 at the flywheel will need around 32# injectors, stock won't get you reliably passed around 350 flywheel unless you go over 80% duty cycle, which is bad for your injectors accuracy and spray pattern.
