I did an EGR with Deviant block plates. DPF DEF delete just a 4” straight pipe. Kept factory tip. A S&B intake. EZ LYNK tuner with Motor Ops tunes. Now I can’t drive my truck. I barely can go 5 MPH. I have no gear info on my display. The manual shifter doesn’t work. I have no idea. I put the factory exhaust back on and went back to the “factory tune” but I think something happened to the TCM. I don’t know what else to do now. Any information would help.
You could try to reload the tuning files. After that you need to call the tuning company.
I have contacted them multiple times and got no answers. They say everything is fine with the tune. I have tried several times retuning it and got nothing. Still same issue. I have checked over everything making sure everything is plugged in correctly.
