i know.. i know.. but ive seen a powerful cars making alot of power tuned with WB..after to read (not completely still) about tuning.. it's very important to tune with WB and not only by reading plugs.. :y you need to get a A/F specific depending what car (sometimes) so... a WB will let you if youare runing 12.5 or 12.8 for instance..that's what i think ..if im wrong then.. sorry :8

Anyone that is worth anything will...at least everyone I talk to on a regular basis does. I and others will even pull them on the street after a session sometimes...

for sure, specially if your runnig a hack and msd boost retard, you can tell everything by the plugs and i still pull mine atleast once every two days and change them about every 2-3 weeks (sometimes less)

Yeah, but I could tell you if you needed to run that rich/lean based on how the plug looks.

I met a guy who could guesstimate with .5 AFR just by looking at the plug. I called bullshit, did a pull in the car I was tuning and pulled a plug I was at about 11.0-11.3 during the pull and after looking at it for about a half second he said 11.5-12.0, he knew nothing about the car, being his forte was domestics so needless to say I was impressed and got a bunch of other free advice while i was there :)

There might be some small cues in the well and on the outside ring I don't know to look for, but the ceramic and ground strap looks more or less identical for anything well-tuned at WOT, from my 13.8:1 AFR B7 to a 500 whp 11.8-12.0:1 car.

This might be off topic but I saw a site posted on here about certain plugs under certain condition. Can some post this link up if you have it. Pictures tell a thousand words...
