[Gmecm] TBI conversion

[Jared Ryan]

I believe that is correct.  I had to change the MAP sensor when I 
converted my CCC El Camino to TBI.  I used one specified for a full-size 
pickup.  The CCC carburetor system also had a barometric pressure sensor 
under the dashboard behind the glove box, separate from the MAP sensor.
