Had a Bully Dog Gt recently installed and this warning popped up on the dash after about 300 miles. The Bully dog is not picking up any codes. The DPF has been removed and the EGR is only disabled. 2010 Ram 2500. 36,000 miles. Any one else get this error? Also thoughts on EGR being disabled versus removed?

I got the same thing I just posted in another thread, got a u12a4 code. Had the same programmer on the truck before but uninstalled and had the emissions update done. Reinstalled and now I have service exhaust and 150 miles till reduced power.
