MAP sensor?

I've been trying to figure out how to get my HPtuners program to monitor the boost from the twin turbos, but apparently I need to replace my stock 1 bar MAP sensor with a 2 bar version.

First off, where the heck is the MAP sensor located? Is this something easy to get to and replace?

Secondly, will any changes need to be made to the tune after going from a 1 bar MAP to a 2 bar map?

And thirdly where can I find one of these 2 bar MAP sensors?

I would like to be able to set up the scanner on HPtuners so I can actually see when boost comes in and how much at what RPM levels.
 
the map sensor is the back of the intake. I was logging boost with a 3bar map sensor. not with HPtuners though. but I just unplugged the original sensor harness. and rewired the harness to the 3bar. it was just a power ground and 5volt reference and connected the vacuum hose. i got it from the dealer with harness for like $70 list
 
Ah! That doesn't sound too bad. So the dealers carry these MAP sensors? Well, I'm sure mine doesn't. I may have to see if I can rustle up a part number and then find one online.

Thanks.
