That depends on other things. Is your smog pump hooked up?
Are your O2 sensors good? What other mods do you have?
The more mods you have, the more emissions your engine is going to produce.
I'm not saying a modded engine won't pass emissions but an engine that is stock or very close to stock will have a much easier time passing smog tests.
