Where to start?

[Jarhead79]

If I loop the dpf pressure diff switch and remove dpf filter will this help some? Also trying to figure out the egr? But if I do so I still need to do ecm for turbo speed and non egg modes? I'm clueless but trying to soak it in fast as possible. I'm not trying to run ckoked up engine and pretend to like what it does to the engine. My truck will run the way I say it will.
