The BOV in the kit comes with an 11psi spring, since the vacuum falls in that range with the stock engine. A shop like AAM should know this. |
Well I found two things, 1. They did not tap the manifold for the vacuum lines for the blow off valves; instead they used the big vacuum hose that goes off manifold into the firewall and t fitted twice off of it. I will have to wait and see if they found the vacuum at idle and ask what spring they used.
2. My car on their dyno sheet hit 15.5 pounds boost, so should I find the vacuum and use that to detriment what spring I need? Or is he using the boost controller to control the level of pressure so he doesn't need to change out the spring? AKA can i do it myself( which i'm not sure i can do)?
Is my car ok at the moment?
