yeah mine also is a t4 twin scroll, could be a 1.06 actually come to think of it, I originally was going to go a t4 0.84 but glad I didn't as boost comes on so faarkin hard as is, is hard to tune the gate pressure in properly...
im running twin precision 38mm gates with 2 springs equalling 14psi I think, will double check that,
will definatly have to catch up, would like to check out your setup and pick your brain a bit haha
edit; I also got my manifold and housing ceramic coated, and heat wrapped my dump and screamers but HOT!!!!
