Vbulletin 6 header

What code would you use if you just wanted to center the logo without stretching it?

#header .site-logo img {
    margin: 0 auto;
    display: block;
}

Then I think the system is resizing the uploaded image based on the configured maximum size in the Attachment Manager in AdminCP.

If you want, you can stretch the image to force it to fill the full-width by adding this additional CSS:

#header .site-logo img {
width: 100%;
}

I am still looking into this. Do you think it is this setting resizing it? I found this in attachment options?

I also was looking at this

That GD option is for quality and not dimensions.

To avoid the uploaded logo image to be resized, simply upload the file directly to the server preferably in the "images" folder. Then go to Style Variable Editor (for each active Style/Theme you're using) in AdminCP and then edit the "titleimage" variable and set the image URL to the path of the uploaded logo in the images folder.
