Doesn't seem likely as the wastegate is an integral part of the turbocharger.

Can't find it on the Forge website.

Do you mean wastegate actuator?
 
From the look of it, it has a slightly stiffer spring to delay the wastegate opening a little, which will increase the maximum boost. I can't see this working well without a remap, unless the boost increase is so small as to not trigger limp mode on the standard map. But I don't know what the tolerances are.
