Also changed my wastegate boost reference from the turbo compressor to the intake manifold. I was finding that I'd start out with 5psi boost, but it would steadily fall to about 2psi as the engine reved higher. Today I had an epiphany - it's probably losing 3psi through the intake piping and intercooler, and only 2psi is getting into the engine. I will test the relocation soon.
