98.524v

I bought this truck a few months ago (stock turbo, Edge Comp[sold]) truck had a hard winter, fuel jelled up a few times, my truck always had great power and smoked big clouds and would make 20-30lb all day, i found out my fuel pump (air dog 165) wasnt making noise, but truck still ran like a top. Recently i would start my truck and it would be super sluggish, defuel while driving, you could barely give it gas amd it would die. I replaced the air dog, and now have a working lift pump, didnt fix problem.... truck runs better but is still defueling around 60mph (runs better at night time (cooler outside)) someone please help me this is my daily!

If you removed the Edge Comp and did not re-install the stock boost elbow the truck will de-fuel and even throw codes because it gets too much boost.

I'd also suggest checking the fuel pressure and also check the fuel for aeration.
