As stated by chris, we just need to fabricate a new V brace due to the motor mount being relocated. the OE V Brace will not be strong enough due to the relocation.
I would like to know if HPF is continuing to keep the wastegate closed at idle to help improve low end (factory only closes 1 of the 2 wastegates at idle). That alone, would most likely make it rev happy.
