Possibly, I had the guy that programmed my PCM "disconnect" the upstream O2 sensor.

 

I didn't know you could do that.

 

Yeah About Wolf Performance Engineering <--- look at that resume.
They plug into the OBII port with their computer & with the right software they can change almost anything in the PCM. For instance - with my 32" tires & using the Hypertech to change the tire size by 1/4" increments I was still out a little bit. He saw what the speedo said & compared it to what the dyno said the wheels were spinning at for speed. Came up with a formula/ratio difference & entered that into the PCM. Now my speedometer, odometer are dead on!

 

That is pretty dang sweet!

 

Where are they from?
