Okay guys I have to take my truck in tomorrow for warranty work. I removed the XRT program today and put it back to stock. I took the DPF/EGR off the truck...but the manual said to select "YES" stating the DPF is present even if it isn't. I just started the truck up and now the check engine light is on. Is that normal? I just wanted to put the truck back to stock setting since its going to the Dodge garage. When I put the 125 setting back in the truck and select "NO" stating the DPF has been deleted will the check engine light go out??? Any help is greatly appreciated guys.

when you select "yes" present, it will try to regen, so you need to have it in there I believe.

Thanks Shibbyutman, I took it in for warranty work... brought it home reloaded the stock programming since I have been running the 125hp... so I want to try to save my truck a bit... I have really been laying into it... it's so much fun... and I just reset all the other settings and there are no more lights...

OK first we need to look at what you are wanting "Stock" to mean. Do you simply want stock horsepower, or do you want to remove the tuner completely?
The XRT has a setting for Stock horsepower, but allow for DPF/EGR removal with no trouble codes. This is the setting where you answer "No" the DPF is NOT INSTALLED, and then select stock Horsepower.
If you want to remove the tuner completely, you will need to answer "Yes" the DPF is installed(even if DPF is still removed). It will then only give you the option of stock power. This is how to remove the XRT completely.

If you have not physically replaced all DPF/EGR parts back to factory condition, and you removed the tuner completely, then you will get trouble codes. If you HAVE physically replaced the parts to stock form, and you are still getting trouble codes, then you may need to drive the vehicle a few miles, then use the XRT to clear the codes. This should clear the dash of the light and clear any DTCs.

If you still have questions, feel free to give us a shout.
