Hey guys need a little advice about a wastegate, I have what seems to be properly functioning wastegate, but I don’t have the most confidence in it.

It does not slide perfectly smooth, and I am concerned that it could be an issue since I am going to be tuning soon.

Any information someone can give to help me resolve my little concern?

The wategate that is currently on there is 45 mm at the inlet and 43 mm at the outlet, what does this make the wastegate in terms of “size”

Any recommendations if I am advised to get a different wastegate which should be purchased?

The standard seems to be the tials?

And anyone whith first hand knowledge want to explain to me the advantages of plopping down the extra loot for the tial over a standard one? (other than the ol sarcastic it will save your engine duh)
Will it really make a noticeable difference in the way the boost is controlled?

Thanks for any insight.
