Re: MAP sensor location

[Len Sabatine <sabatine@epix.net>]

 A solid mounting as close to  direct manifold  vacuum source as practical 
, FWIW  ,TBI , wet  manifold  need a little
distance to avoid getting fuel into sensor. TPI , MPI etc,  Dry Manifold , 
close as you can get. Production locations vary per
specific engine design , which are usually well placed in normal usage. 
Avoid snuggling up to an EGR feed orifice in plenum.
 Look at a TBI setup , then Look at an LT1.    These are suggestions.
