Default knockoff Tial 38 mm mvs wastegate

So if any of you have been shopping for a wastegate recently, you may have come across this Tial knockoff:

They are asking for about $100 shipped direct from China and claim these are high quality copies. I was curious how this Chinese company is able to use tials design and their product description? they even engrave "made in usa" on the top.

Anyway, I bought one and my first impressions were pretty good. there's no doubt its a copy of Tial's new mvs design. It came in a small white box just like real tial products packed with the foam, 2 v band clamps, 2 banjo style nipples, and 3 plugs for the Ports you don't use.

I did however find something i'm not too excited about. I was hoping someone could comment on how this might affect boost/performance.

you can see in the pic that there's a 1/16-1/8 inch gap from the edge of the wastegate door to the side of the housing. This thing will never completely seal is what i'm getting at.

In this pic you can see the newspaper through the gap
