EGR stall test question

[zukitrek]

Ok, then I was using wrong port. With this one I do have to raise throttle and it will pull EGR main main thru bypass hose to P nipple. Thanks!!

Question, now that you sent the picture, when I was installing the TB I did notice that this hole (red arrow pointing to)    

got covered by the gasket. If this is so, I mean is this correct? Where does it gets vacuum from, if covered. (This is just aside from main topic, just curious)

Although I was using this port, where blue arrow points    
to do the test last night as this had vacuum all the time (right?) and pulled EGR main thru disconnected VSV at P nipple.

Now I see that if I gunned engine it would not have mattered.


Ok, I'll then use this port tonight and let you know.
