Do you have any closer pictures of your wastegate setup? From the pictures, it looks like you are keeping the up-pipes divided into the flange and running a merge in to the wastegate flange. Any issues with that setup? I'm thinking of doing something similar, but can't decide. Thanks.

I don’t have any other pics handy but your description is how it’s run. I have to say the WG works very accurate this way. It has a 7lb spring in it and when I disable the boost controller, it builds boost to right around 7psi. With the boost controller enabled, every 10% of duty cycle adds 1 psi of boost so it makes setting and knowing the total boost very predictable.
