    Are you thinking about using the O2 sensor for just tweaking the idle mixture? Or are you thinking you will do some rejetting? Just curious.

    Each individual header pipe has a test port of some sort - any way to use those so you can measure each cylinder individually??

    Edit - I see you have an aftermarket header, so nevermind the question about the test ports on the stock header pipes. Although it did get me thinking about maybe taking some crusty old header pipes and having O2 sensor bungs installed on them.

    Just want to dial-in the mixture as a whole using a wideband and to get a feel for what's going on during the 6k bog. Don't need exact numbers just a snapshot.
