3 BAR Map sensor and 450cc Injector questions
 

This may be a really stupid question, but I have a GM 3 bar map sensor, DSM 450's *or 390's, haven't picked them up yet*, and a resistor box.

I see how to wire the map sensor and injectors, but my question is do I need to get my ECU chipped to run these injectors and MAP sensor? Also, where should I pull the vacuum for the 3bar from?

I had my old ECU chipped back when I had a mini-me setup, but am back to a Stock PR4 ECU for my B18B1 right now.

yes.

The stock map sensor is on the throttle body, right?
