How can I make my Instafeed full width on Impulse theme?

[NCCShop]

Hello

I am trying to get my instafeed the full width of my website, but right now it has a large margin on both sides.

I am using the Impulse theme and cannot seem to find a code that works.

I would like for the width of my instafeed to be the same width as my website, but I cannot figure out the proper code or spot to place it.

This is what it currently looks like.
