they really don't look bad to me. A little on the light side but how old are they and did you shut off under wot (w or w/o n2o) to pull them?

 

7 is 1 day old 10 passes on the 75shot 3 is a few weeks old pics are from the next day, I know I should pull right after the run, I will next time.

 

7 looks a tad rich, but not bad. 3 looks slightly lean.

I remember the pre-wideband days...

 

on #7 there are some speckles on the electrode. Wipe it with your finger and see if they are metalic. That would not be good.

If you drove on these, reading them now is useless. It really has to be done at the rpm/load that you're trying to read for.

 

I have the dynotune LC1 but wanted another opinion...

Trying to read a plug after it has been drove on is a waist of time. It washes the plug.
You need a wide open pass and then instantly shut it off.

I don't intend to hijack, and this might be a stupid question, but how are you guys pulling your plugs after a WOT run? Also, which ones are you choosing to pull, and why? Obvoiusly I'll use a socket, but my engine and exhaust get just a little warm after a WOT run... I don't want to burn myself, ya know?
