Actually there is a section defined for Site Title and Ad section. The text you mentioned is made centered respective to it’s ad section. It will be a bit tricky to make centered as based on screen width because of Site Title placeholder. If you need to make force centered look then please add the below custom CSS code we have created the code base on your logo width.

@media (min-width: 1200px) {
	.navbar-head .col-lg-4 {
		-ms-flex: 0 0 auto;
		flex: 0 0 auto;
		max-width: 100%;
		width: auto;
	}
	.navbar-ad-section {
		text-align: center;
		-ms-flex-preferred-size: 0;
		flex-basis: 0;
		-ms-flex-positive: 1;
		flex-grow: 1;
		max-width: 100%;
		padding-right: 260px;
	}
}

Thanks
