I restate my question of whether or not you were able to upgrade the MAP sensor to gauge the amount of pressure in the manifold, or by retaining a mostly stock setup do you plan to simply adjust the fuel tables and VE to go around the problem.

Ok now sam answer my tech question

(oh and it's been almost three weeks now are my test-pipes still on back-order)

Let start with map sensor, the map sensor that you're seeing is a very low range map sensor or in a better way to describe, it is a barometric press sensor, It is mainly there for altitude compensation.

The key of placing the intake temp sensors as a blow through is to give the ecu the most accurate info possible so the intake temp compensation can be effective .

If you place the sensor in draw through setup, compensation for heat soak condition(for example) will be impossible and if you put it in the charge pipe (the stillen kit) then you are always reading the hot air out the blower .

Therefor placing the maf sensor in a blow through will gave us the most accurate reading of air temp before entering the engine.
