Backfiring and sooty plug

Had a mishap with #7 this week myself. Not blaming the truck intake as the root cause but I will not be using it on my 6.0 build . http://i1057.photobucket.com/albums/...psc7820a83.jpg

that isnt intake issue. that is coolant temp issue with too much timing and lean AFR....cylinder temps got hot, egts thru roof

That's why I said I was not blaming the truck intake as the root of the cause.

I'm going to stick with the truck intake for now. Going to send the injectors out to be cleaned/flowed and go from there. Also going to try and get back to running at least 50% Ethanol fuel for added safety, along with the water/meth i'm spraying.

93 Octane, with a sno perf kit. I only have 10% Ethanol here in Jersey. I don't really "blame" the intake, but changing it reaped me better results in my favor changing it out, and i had better luck with the setup after it was changed. Must have been a coincidence lol. I had an EGT gauge in my truck and it would scream until I started spraying it with meth, then the heat levels came down to a much happier level when I was beat the snot out of it.
