Yep vaccum line right where you said it was. And lo and behold follow it and right there near the firewall is the map sensor. Can't believe I never saw it before. Plumbed in and the gauge reads boost now. Thanks Bnaylor.
The SC is pushing out 8-9psi. Seems that is what it should be so the SC should be solid. I am getting ready to replace the coupler and bearings in the front. The needle cup bearings on the rear has anyone had experience with them? Are they something that should be replaced as well?
Also I have had no luck finding any other option to the gm SC oil. Is there a synthetic available? And boy that stuff smells as bad as Limited slip additive from Kendall.
