Thanks @Ed @ EQT. I’m going to be taking a look at the DV to ensure its assemble properly as I had to swap that from my is20.I'm not sure how you set up your boost leak tested, but generally the two things that don't get tested are the DV and compressor outlet connection (TMD o-ring and the coupler/clamp that connect to the discharge pipe. That's where I'd look first. There's no good way to test the DV without swapping it out.
