    Is there any way to get egr on a 3 bar tune? 2005 Silverado.

    Like many, I have my wideband hooked up to the egr input of my computer. Little did I know, once upgrading to the 3 bar, I lost the egr enable option.

    Can I send my tune in and get just that one option added kind of like a segment swap? Wish I knew about this stuff before, I would have done the wiring different. I ran the truck 1 bar NA all of last year so it wasn't a problem until now.

    I dont believe this can be turned on. Its an easy fix however. You can use your ac pressure input. Using ac? Use fuel tank pressure voltage.

    Fuel tank pressure. Good idea! I didn't come across that one while searching about this problem. I've seen the A/C sensor before, which I am using A/C. I did delete the fuel tank pressure sensor though so now I can use that. Thank you.
