[QUOTE="Blinkwow74, post: 16288185, member: 150930"] Ok so put it back together and went to the highway to check it out. I still don’t have the throttle response I had after it was tuned.... just feels lagging....so if I floored it really quick it the vacuum went away and it started climbing to a max of 3 psi maybe no hissing until I let off the gas.... If I’m just driving normal and start to accelerate the vacuum goes to zero or almost zero then falls to negative again like really has no power. I seam to remember having better throttle acceleration when I was N/A..... So I’ve tested the bov with out the vacuum line hooked up and yes it’s doing the same thing....but I didn’t let I run in that configuration very long I tested it at sitting no load. So question could my intake manifold have a hairline crack? Not sure if these are the symptoms I would see.... 1. Vacuum hoses are good no kinks nor cracks. 2. Tial BOV seams to be functioning properly when tested with a hand vacuum tester per tial’s tech support. 3. Brake booster isn’t a potential bad part because like I posted before I took it out of the equation. During a troubleshooting session. So this is getting very frustrating I want the car back that was crazy scary before this happened. [/QUOTE]
