Hey guys, i need your help!

I have the following error code P0401: Insufficient EGR Flow :doh:

1. My truck has EGR valve. Somebody can send me some pictures of the location of this?

2. Which is better/performance: with or without EGR valve? :confused013:

3. I need the EGR valve? :sad2

Thanks!

that WG control wont work any better than the stock system since it only vents off the rear 3 cylinders because of the dual scroll manifold and turbo.

Im confused on what to do with the vaccum lines, you say you just ripped them out, but a little bit more detail would be nice. As i feel like it is kinda valuable to the health of the truck

I’m sure he got it figured out 13+ years ago…

Nevertheless, pic is good for future reference.
