Just did my egr delete on my 6.4 started it back up for first time and wrench light is on in the mileage /info display. what does that mean. My code reader doesnt read any codes

What programmer are you using? Spartan requires you to download their EGR delete tunes from the site, SCT requires custom tunes AFAIK, and I am not sure about H&S

Plug the valve and the EGR temp sensor back in and see of the light goes off.

Suspect your tuning turns the function off but still looks for the parts.

If your dpf is still on then even with a tuner your light will stay on bc the dpf is clogged up. I did my egr delete and my light wouldnt go away even with my mini max so i did the dpf delete and intake and reprogrammed my truck and all is good.

I dont like the h&s, nothing against it, just not what i want. I like the availabilty of so many different tunes with sct. And i dont even leave it plugged in and use the gauge function, same way with an h&s. I dont like the big GPS looking unit always on display. I have an aerforce scan gauge so i can read all the same parameters just mounted in a regular gauge pod.
