Can someone check out my plugs and tell what they say???
Hey guys, I just pulled my plugs to take a look, fuel pressure is a little low at 30, just wondering what the plugs are telling me. Thanks.

I assume you pulled these after you let the car idle? Do a pull. Turn the car during the pull. Then take pictures of the plugs. The plugs are going to show the last combustion event(s). Do you have a wideband?

the car definatly runs really rich at some point (hopefully in boost 
). the base of the plug is covered in soot as is the insulator. The heat range looks good for the setup. cat really tell anymore on such a usd plug. put in new ones and shut it down at full boost.

he forgot to mention, he's boosted.
it almost looks like your car will run rich then go to lean being that your insulator is white as hell.
as already said. your fuel pressure should be around 45-50psi. get a wideband, see what your AFR's are and report abck

Yes the car had just been idling. I'll have to try it again, Im having issues with fuel, I don't seem to have any leaks, maybe i'll just turn the pressure up on the FPR. its an AEM, anyone know which way to turn?
