I am currently running a Dynotune Wet Kit , 100Shot on a '03 Z06 with bolt ons...

Last night everything ran fine and I had no probs. This morning I went to check the plug conditions and found this...


Sorry for the blurry pic...

From what I can tell the electrode is perfectly fine, no rounding or chipping. But there is a white powder lol, on the electrodes... Now when I rub my finger over it, the powder goes away and the electrode is browninsh-black, which tells me, the car is running rich like normal. Is this white powder caused from the sulfur in the nitrous?

 

Sorry dude, maybe someone with better eye's then mine can help you out.

 

Are you using an octane booster/fuel additive?

 

Nope, just 93, and the plugs before these were the standard rich looking plugs...

 

The green tint on the strap means the nitrous is working properly.. it looks good to me.

 

Cool, thats what I needed to hear.

Dean @ Dynotune attributes the white powder to a fuel additive as well. I am going to fuel up somewhere else next time and see what happens.
