Question to the California guys.
Not to sound like an *** but WHY in the name of all that is holy did you tap in your boost gauge to the regulator line on the fuel rail?
If your boost gauge develops a small pin leak your going to of coure experience less fuel... Do me a favor replace the line to the regulator with fresh 1/8 vacuum hose and see if your AFR drops.
