Well my FDC was already bypassed by the depot. I have boost and EGT waiting to go in now. I figured I would pull the turbo to tap the hole for the EGT and might try a C turbo at the same time since it's out (have a D now). For boost I'll probably just use the hole that is already there for the ether injection. Once I get a baseline I can adjust fuel and droop as needed but din't want to mess with that until I got the pyro gauge installed. I assume the depot is running everything at a very conservative level but will be sure before proceeding. From what I've read there isn't much difference in HP from a C to D- basically just the sound.
I wouldn’t adjust droop unless it has issues starting. Even then I’d look at other things that could be causing that first. Adjust the fuel and smoke cam. D turbo will make more power if you adjust the fuel and smoke cam, like you said after pyro and boost gauge installed. You don’t need to remove the turbo if you still and tap the hole while the truck is running, but obviously the better thing to do is to remove it, blow out the hole and shop vac the manifold during doing that.
Unless you really want the sound, don’t swap turbos. A D will outperform the C it’s a more efficient design and will flow more air. Not that the LDT is much of a powerhouse or anything. Adjusting the fuel will really bring the D turbo to life. More fuel equals more air flow equals more power. The C can only go so far.
There’s a few videos on YouTube how to adjust fuel settings. Check out the one by member Jeepsinker (aka Garrett). His channel is called Tactical Repair. Lots of good stuff, I’ve learned a lot from him. Subscribe to it.
