No different wether the jb4 was in or out as so long u adjust it to map 0 cos everything is off on Map 0.
I just came bk with a run, the jb4 is reading about 1-2psi higher or lower than the dashcomm linking to the ECU. Nothing related to the AFR cos my is a wideband sensor. Don't know why you always like to wild guess lol....
