I need to replace all my fi's and have a few questions.

First: What is the poundage on the stock 02 Z06 fuel injectors?
Second: Anyone have any good reccommendations for replacement ones?

I have LG longtube headers and Xpipe with cats, a Vortex ram air inuction. Other than that, everything in the motor is stock, so I'm not doing too much more than the stock hp.
Thanks for your help.

 

I use Racetronix injectors in my Grand National. I am running 42.5lbs injectors for a 600hp forged and alky injected V6 with almost 25psi of boost. If you plan on any more mods, I would go with maybe a 36lbs injector. Good luck

 

Take a look at this thread.

The SVO 30's will flow 36lbs and will be good for stock upto heads and cam ect. at least on stock cubic inches.....

 

Your injectors are 28.8 lbs, this is to answer your question

 

Why do you need to replace your injectors

 

Coming back from BG two years ago, the car started losing power and i couldn't accelerate. It was shaking violently when I tried. I managed to get it home and found out that the number 7 fuel injector was shot. So I replaced it and didn't have any trouble till recently.
I only have 21K miles on my 02. But this summer when I drive it for any length of time (around an hour) on the highways it starts jerking and bucking. It only happens when the engine is hot. If I let it sit overnight or back way off the gas to about 35mph for a while, it works itself out. I've had it in the shop and they checked all the FI's and they say they're fine. I've checked the wiring harness and it's not rubbing or cut. I've checked spark plug wires and they're fine. So my thinking is that one of the FI's is sticking occasionally and rather than mess around I'll just replace them all.
I have a Vortex ram air and LG long tube headers with Xpipe and cats. Those are the only engine mods I have. But I've never had it tuned since having that done. I've gotten several replies on other forums that this may be part of the problem.........that with these mods I'm running too lean without having had it tuned. I honestly don't know what to do. But would running lean cause it to buck? This is my first Vette and where I live, there isn't anyone around who knows what to do or to do a tune.
If anyone knows anybody close to Western Pa who does tunes on Vettes, please let me know. I'm open to all help.

 

Maybe the fuel pump is shot, not the injectors?

 

You might just need a good dyno tune...I'm running with stock injectors and having no issues. Heads, cam and all bolt ons. 450rwhp/432rwtq...

 

I agree a tune would probably help..............do you know anyone with LS1 edit and the data logging softwear?
I'm getting my tune redone next week with new SVO 30# injectors and the guy who is doing my tune lives in another state.

It might even help to get your stock tune reflashed just for any GM updates..............I'm doing this to get rid of the mess my 1st tuner did with my car.
