I want to know where is the best place to mount the probe. I know it says 1-2 inches from the head on the manifold but i have headers. So do i just pick one tube and go with it or do i put it by the collector? Also what temps to i expect to see at idle, cruise speed, and wot? If someone could school me that would be great!:biggthump cough cough...Bob...cough lol
