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.. 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

 

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.

 

 

I told you man, and you thought I was smoking crack

 

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...

 

Ummmm Det cans anyone?
