its a 99 b18b with a garret t3, dsm 450s. stock internal wastegate, and I had a ss autochrome manifold re-welded. Im supposed to be at 8 psi, and its hitting 10. Its socketed, basemapped using uberdata.

Im just running the vac line from the turbo and wastegate, and just hitting 4 or so psi. My exhaust is 2.25 the whole way back.
