I'm just learning about this so bear with me if this is
too basic. 

I was tracing out the wiring on my Jeep wrangler, and found the O2
sensor has 4  wires, I was aware of the three and 1 wire config,
But what does the 4 wire do differently??

I'm trying to asses the potential for a forced induction system 
to get about 20 more HP out of the 4 cyl engine.....

Any sugestion please speak out :)
