Yep but I would not t into that as it will fudge the map sensor. Not by much but data does not lie. I would tap a new hole somewhere just for the boost guage.

I have seen heaps taped into the steal pipe from the turbo to the intercooler. Easy to take off and drill I guess. 4 10mm bolts and a hose clamp.
Also if you tap into the map hose you will get fluctuations in the reading due to the throttle plate opening and closing as it needs to. By putting it in the pipe you will get the exact boot reading uneffected by the egr and throttle plate
