I've been testing it both ways. Full vacuum and ported vacuum. I'm running a limiting plate. Finally got my transmission kick down set perfectly. Then, the Steer and Gear rebuilt power steering gear developed a leaky pinion shaft seal. Long story, but I'm pulling it out and sending back for warranty work (fantastic customer service btw). So...I'm off the road until I get it back. As Rusty says "Back to our regularly scheduled program".
