i am ordering the turbonetics gt35r killer t3/t4 turbo
i am gettin a STD longrun manifold from JSP
they are asking me about what kind of wastegate flange i want to put on i dont know what size i should get i was looking at TIAL recommended but i dont know i will be running a dual stage electronic boost controller
running at anywhere from 10psi to 25psi wondering which kind of wastegate from tial or turbosmart i should get so i can tell them which flange to put on any quick info would be great thank you

 

Tial 44mm. that's the Vband one.
