I had my stock HX35 showing signs of failing, and before it completely failed and caused a catastrophic chain reaction I changed it out to an ATS Aurora 3000.
The new turbo is spooling fine, however now my performance is worrysome.

With the old turbo, I had excess black smoke because the fuel screw, or "smoke screw" was turned up. Playful yet manageable coal rolling with performance comparable to stock, No crazy horse or torque numbers. No other fuel mods like turned fuel pin or ground fuel plate. Those haven't been touched

Quick disclaimer, I do not have any aux gauges for fuel pressure, boost pressure, EGT's, transmission temperature, oil temperature. No auxiliary gauges whatsoever, just the ford gauge cluster from the gas motor in the dash.

With the new turbo, the truck acts like its running lean. While in park, if the accelerator is slowly pressed, the RPM's do not climb steadily. It staggers somewhat and seems to reach its limit prematurely. In drive it doesn't have the same problem (to the same extent at least) however it acts like it runs lean. While during a quick test drive, I started smelling hot metal. I return home and pop the hood to investigate and the header was so hot the unpainted metal was smoking and the heat mirage was easily visible even at sundown. High EGT's, right? The thing is, I think it's running the least amount of fuel it has since I got it roadworthy. This conclusion I reached based on the now absence of black smoke. From what I understand, it's more fuel that leads to high EGT's, not less, so I have a theory that is not backed up by the fact of high EGT's.

I'm mechanically inclined with both diesel and gas engines, but I'm not a grand master diesel tech. Is there something I'm missing?
