Who has a walbro 255 fuel pump with mostly everything else stock(ie:no turbo), and is running richer than before?

Theoretically it shouldn't make the car run richer due to the stock FPR. I know this, but i want to hear personal experiences. I did a 20 minute search and read all posts/threads i could find. Seems like most agree that it will not cause a rich situation, however some of the posts disagreed. Want to hear if anyone PERSONALLY experienced a rich situation or a faulty FPR. Thanks.

Reason i'm asking is because i need to pass smog, and debating on installing the F.P. now.
