Maybe the MAP Sensor Chart, see attached pic, will help? The MAP sensor will produce a voltage based on Kpa (pressure / vacuum) felt by the MAP. The computer will adjust fuel and spark based on the MAP sensor voltage.
How much fuel, and how much spark advance can be changed / programmed in the fuel and spark tables of $OD.

I'll check out those turbo ecm'
From what I understand my ecm is capable of multi port with minor mods.. I want to eventually step up to mpfi but wanted to use the TBI as an easy learning tool.
My turbo is a draw through so I think that may beneficial..
I've read that a guy using a super charger had good results using a boost referenced regulator.. not an FMU but a 1:1 ratio regulator..My ostrich arrived today! Unfortunately I'm bedridden a few days because of an auto accident I was in Tue afternoon broken foot and dislocated ankle.

Thanks Dave that should be very useful.

Here's an interesting question...
Ok my Turbo is a draw through style meaning it sucks air through the carb or throttle body. Since this is the case, if my vacuum port is before the turbo, shouldn't it always register vacuum regardless of the type map sensor? If i put the sensor on a line off of the intake it would read boost or vacuum... I'm thinking the map sensor in stock location on the throttle body should be good and adjust the tables to deliver more fuel in the areas where boost is present and add more fuel however necessary.. Should make for a pretty mild tune for normal driving while not in boost? Lots to think about here lol
