Hey guys. I have a 2015 6.7. Got the P20E8 code.

Tried two OBDII readers to reset and it does nothing to the limp mode timer.

I looked at the DEF pressure and it was about .5 psi, from what I can tell it should be around 50.

I am not 100% that I am looking at the right point.

This brings me to the decision of deleting or buying the 1200.00 pump.

If I replace the pump with limp mode go away once the pressure is up?

I am sure that the stealer has a way to clear limp mode, but I can’t figure it out.

Pretty new here and I am aware that the EPA is cracking down on tuners.

If I do delete, What are my best options to look intact?

Thanks all all for the help.
