I put a 3 Bar Sensor on the blower when I installed it for the intske mixture or whatever, but my tuner did the rest. I assume he changed the sensors because I had to go to the parts store and get him 2 replecements for his inventory.

the O2 sensor is in the exhaust stream, its reading is the AFR (air-to-fuel ratio).
Lean = high AFR
Rich = low AFR
A "3 Bar" sensor reads "manifold absolute pressure" (MAP), or "boost" in a supercharged engine. It won't read "lean" or "rich" because it isn't a fuel mixture reading... its just reading the pressure of the air before it goes into the cylinders.
