Is this even necessary if one has a juicebox pro? Just curious because I just got a JB and had heard of the o2 modifier, but I think I read someplace that it is unnecessary.

My understanding is you have to use the stock o2 with the juicebox

You can use the O2 mod with the regular Juicebox just fine..... works well.

Not sure about the JB pro.

The o2 mod basically tells the Spyder computer that you're running lean and to enrichen the mix....

I'm upgrading to the Power Commander V with auto-tune, so i'll be going back to using the OEM o2 sensor signal... along with a wideband sensor for each cylinder that the PC V reads.
