There is no vacuum to the ALDA. The vacuum to the "IP" is actually to the vacuum valve for the transmission, which just happens to be mounted on the IP, but has no affect on the IP itself.
The only impact that I can see on engine operation (due to lack of vacuum) is that the EGR valve won't work, if it still worked in the first place.
