Sounds almost like the point you've tapped the plenum/manifold is above the throttle plate!

I'd also plug a standard analog gauge onto the port you've used to see what reading you get. Should be like 16-20in hg or like 50-30kpa (might have done the conversion to kpa wrong in my head there!)

Have you broken the feed line to the relay and measured exactly what current it's drawing?

I'm sure someone else can chime in with what the 2222 can deliver, faster than I can thumb through my ECG book. ;)
