Can EFILive be setup to measure and record Boost at the intake manifold?

It should be possible. Maybe a little tricky. Several members have plumbed the signal from a wideband O2 sensor into the PCM to record in EFILive. They have been using "unused" or "non-critical" factory sensors (like rear O2s or A/C pressure sensor) and feeding a programmed output from the WBO2 into the PCM that way. I assume you could install a 2 bar MAP sensor in your intake (in addition to the stock MAP sensor) and send the 2 bar signal to the non-critical sensor input of your choosing.

If you can wait a little bit, EFILive verison 7 is due out soon with two analog inputs added to the scanner cable for any 0-5V inputs you like. No hassling with trick wiring or disabling sensors...
