I have had 3x motors with boost give me a sooty #7 plug, as well as three broken #7 pistons on each motor. This was when using stock truck intake. Switched to TBSS intake, problem solved. Sold the turbo as well as solving the problem. I blame sooty plugs on poor flowing truck intakes.

What kind of fuel were you running? Were you spraying Meth?Originally Posted by MrHorsepowerLSx
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.
Big slow mud truck with a TUNE!!!!!!
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 .

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

it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
That's why I said I was not blaming the truck intake as the root of the cause.

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.
