I'm checking to see if anybody with a 07 and cipher has had false readings in the AFR W-b1 and 2.I'm getting a 20 at idle and 13 at WOT.I'm running a 6.7 in the 0-60.People are saying that i should not be doing that good if i'm realy running that lean.Also i should be throwing a code witch i'm not.Anybody else running this lean at idle?
