Well finally got everythings hooked on for my turbo charged civic, I don't have a guage, so I don't know if it is boosting. can't hear anything cause I still don't have my downpipe connected to the cat yet.

How can I tell if its boosting. also the blow off vavle makes NO noise, I haven't put in the check valves yet. So I know I should see the check engine light.

What should I do?
