Ok.. so last night i finally got my new sfmu installed. I couldn't mount the unit in the engine compartment without removing the cruise control. So.. there went one luxury.. Anyway, I removed the vacuum box thats bolted to the back of the engine and capped off lines etc that was for the cruise control..
Usually on the 420a, all of the vacuum lines are T'ed into each other off the intake manifold. Well, I decided that since im taking out some vacuum lines that Ill just run individual items off each port on the back of the manifold.. like the vacuum for the sfmu, bov, boost gauge.. etc..
Well, today, i was driving my car and i noticed my greddy type s bov hasn't been blowing off as easily as it did before, and i was running 10lbs of boost before, now im only running 6lbs and i didn't touch the boost controller.
Im wondering if i have somehow screwed up my vacuum lines and I actually need to have them all T'ed into each other like how they were before. As far as the BOV, couldn't I just loosen the valve on top and it should blow off easier?
Oh and two more things, I removed all the EGR crap in the car. Has anyone ever done this? Also, Ive noticed that my RPM's dont drop as quick as they used to, I think thats because the BOV isn't getting rid of the extra pressure as much as it used to.
Anyone have any idea what im talking about or am I just rambling?
