Hey Jake, not getting on your case or anything, but the archive is a
great place to find questions like that.  Here's what I found:

>MAP sensor part # for an 84 Chrysler turbo (2 bar absolute):  P5249052

87-91 GMC Pick-ups 4.3, 5.7, 7.4
90-92 Cam/Corv/Firebird v-8
87-91 Chev P-U 2.5
97-91 Astrovans v-6
Come to think of it any Throttle Body Injected Chevy Buick Olds Pont
Turbos with MAPs are 2-bar versions (GM, Chevy, BOP)
A-Grnd
B-v out
C-+5

Thw 2 bar is from Syclone, Typhoon, Sunbird..
The 3 bar runs a boost gage in a '89 3.8 turbo TA

Apparently a MAP sensor stamped "460" is a one bar sensor
