DD15 LOSS OF POWER. INJECTORS or BAD DPF DELETE???

[Andre_The_Giant]

If I were you I would but a new EGR, and DPF, and put the original software back on the computer for the time being...Unless you had a software engineer tune your demandate... or someone recommend on this forum.. it’s most likely a terrible tune. And your driving a ticking time bomb. Call around to multiple places and ask for parts quotes. Get the part numbers. Ask them for better prices. If they tell you “we don’t play that game” simply tell them you would be a bad business owner if you didn’t try.

I wish you the best of luck, spend as much time as you can in here learning how to fix things yourself and trying not to rely on shops to to diagnose things.
