Tail Clamp reading
I tune using the LM1 Tail pipe clamp.
What are guys finding the differance between the tail clamp reading, and hitting it in front of the cats at a bung???
Im high 14's -mid 15 % AFR at idle and and cruise
WOT im high 11s- low to mid 12s AFR.

I often have the dynojet tailpipe in a car, but I always have a portable wideband in a front bung. The dynojet reading is anywhere from the same to 0.5 leaner than then upline wideband, and the lag would make it a little harder to use.

On a Dynojet, the Dynojet's tailpipe reading is approx. 0.8-1.0 AFR higher than the reading from my wideband which is located before my cat.
