fuel pressure on my 94 GT

[Stock50]

what should the fuel pressure be on my 94 gt? it has stock heads and bottom end, it has 24pnd injectors,f cam and a trickflow upper and lower?

I'm not sure, but the stock pressure is supposed to be around 35-45 psi.

Is your exhaust stock? Which headers do you have? You are probably looking at 40psi min.

I wouldn't guess. Do a wide open throttle run and pull a plug shortly after. Adjust up or down according to the color of the plug. That's how I do it. For your mods you will be in the area of 36-41psi.

k...now that his got answered and i dont want to start my own thread on it. how bout me?? mods in sig. i usually have it at about 41ish but was thinkin it might be high cause it smells like too much gas but the plugs are pretty white.

White plugs are fine. You actually want a clean, whiteish plug; this means the plug is getting hot enough to self clean.

Actually Jon, white means lean. You want a dark grey. Black is too rich, back it down some.

I originally typed that Vibrant; then I edited it before posting, because I got mixed results when I double checked my sources. Thanks for the correction.
