I have done a lot of tweaking to the tune in the past. But that's when the t-case went bad so i couldn't use the new power. Not the stocker is back in and she gets it hard. Low boost pulls hard as **** and clean. High boost is the sputtering like mad. When I put the new cam in back when I ran the 12.33 high boost was lower due to the cam. My controller was froze up so I couldn't adjust it. I finally fixed it last year and that's when the t-case ****. So I guess it has to actually push the truck now instead of wasting through the case. And so new plugs? This is all kinda theory of why it ran fine until now. Lol

They can be hard to find, I had to order mine. Projected tip means the electrode sticks out, like the tr6, non projected pulls it back inside the plug if you will. It helps resist detonation.

THose br7ef plugs. Cracks are welded up and she sounds much better. It seems to have more gurgle to it now though. And I think the turbo is spinning faster at idle. She sounds like a Dmax at idle. The exhaust not the engine. We thought something was rattling real fast (hard to explain) kind of a hum. I think it's the turbine wheel just spinning. It could have been doing it for a while. I wouldn't know do to the damn cracks and leaks.



wtf is non projected. Excused the ignorance.
