I will be using a gm 3 bar sensor with a multi function hub, PC3, and FMU. Couple of questions, Where would you tap into the voltage for the 3Bar sensor, would you pigtail off the stock IAP sensor? And: would you use the plenum for boost reference for the 3bar sensor, or could I tee it with the stock sensor? I will be flashing the ecu to raise the voltage on the stock sensor so the FI light does not come on, so I thought a T to this line off the throttle bodies would be more accurate to use, and not have to use a check valve. Any input would be apprectiated Hope this makes sense
