What is an acceptable dip in afr on a shift. with my sd setup it swings down to 10 then up to 16 before evening out at 14.7. im running 12 on the tip-in to compensate for the lean condition. is this normal for speed density? i have been running it this way for a few months without problems but im now wondering if i can improve throttle response by fixing the issue. any thoughts? also my wideband and the afr est are way off from eachother durring a shift. if the wideband is 10.1 the afr est will be 18.3 or so. is that related?

Oops meant to post in tuning tech. my bad.
