    The reason why I ask is I was under the impression that 89 and newer TPI use MAP sensors right? My 92 has one mounted on the side, like this Vette does:

    But I cant find a single unit like the one my camaro (MAP on the side).
    You can add a vacuum port or tee into the fuel pressure regulator vacuum port and run the MAP off that.

    You would not want a MAF setup if you can avoid it because you will need a cold start block off kit. The 1985-86 F-car and all Corvette TPI lower manifolds are also not drilled at the correct angle for the truck heads.
