Make sure they are 100% hollowed out empty and not just with a hole drilled through the center, or multiple small holes. You mentioned new turbo and actuator. Hope they are still stock and not some aftermarket junk. Same goes for CAC and exhaust manifold - stay with the stock / OEM parts, don't swap with aftermarket parts. Same thing for the head, injectors and any other internal engine parts - stick with genuine cummins parts.

Everything has been OEM parts so far. Pressure checked the CAC and replaced all boots. As for DPF, etc, i'm straight piped turbo back. I completely removed everything. At this point i think my ECM is bad, and not the tune. Truck has a couple "eyebrow raisers" that seem odd, so i might just pull that trigger.
