So I'm new to turbos and this whole spring rate selection has me at a hault in ordering a Tial Q BOV for my car. What color spring are you guys running on your turbo setups? I'd measure my vacuum but my engine is still apart and that's a little hard to do. For my understanding hondas usually run around 22 vacuum at idle? So then I should order the yellow spring?
