Looked and test drove a 2004 Subaru WRX today.
At idle the engine pulled 10 inches of Vacuum, now is that normal?
The Supra pulls 17-18 inches of vacuum so maybe it's because its an 6 cylinder?

^^ haha well see
In 3rd gear it was boosting at 13-14psi.
I dont know if it's me, but 10 inches of vacuum seems a little low for an engine....

I think my STI pulls around 10psi vacuum at idle. The stock boost gauge reads out in MPa, and it is at -0.07 which I think is 10 psi?:confused:
