Did you plug the bypass port?

I plugged it with magnasteel and dremeled it smooth/curved.

Is it leaking at the top of the TB gasket? The 65mm does not cover the EGR cutouts.

This is why the SVT TB gasket is needed & I also add a thin (very) coat of permatex to help it stick. (at the top uncovered part)
