I seem to keep fouling spark plugs. The funny thing is the first set was new ACCEL header plugs and after chasing problems for a while I found that some of those plugs were firing down inside of the threaded part. Then I bought some new AC rapidfires and now the same problem is happening. fouling. I was messing with tunerpro today watching my engine running like crap. Anyone have a few screenshots of your L98 idleing and mid and WOT. so I can compare and see if I can get somewhere. or a list of what the values of certain things should be. please help me. Thank you to everyone that has been so helpful, I seem to be cursed when it comes to getting this thing running.

 

Oh and I have 43psi, 24/lb injectors, chip compensates for them, checked almost everything. This may seem like a stupid question but I have Stainless hugger headers and there seems to be insane amount of heat coming from the heads. I have a 160 thermostat so Man tem and Coolant temp sets around 160 or 175 when driving. can the heat from the headers crack the porsland parts of the plugs on the inside where it cracked the accels. or what the a fluke.
