Guys some insight please

So I’ve recently had both turbos replaced....

It’s been about 3 weeks now and today while the roads were quite I put my foot down a little bit and noticed a whistling sound when going over 50mph.... when the windows closed I don’t hear this only when it’s open..

Could this be turbo related... I f****** hope not

Only sounds past 50mph but when I let go off accelerator it’s disappears
