The sensor hoses can become clogged from soot in the exhaust system just like the DPF. It's going to want to close turbo down and open EGR valve until it see pressure Take the butterfly out of the throttle and leave EGR in place but blocked off with plates Then setup another resistant mosfet to simulate a pressure in the EGR to keep that readiness monitor happy. Monitor these parameters during a regen, and you should have these values; EGR differential pressure - less than 0.5" Hg - if higher, could be stuck open/leaking EGR valve EGR valve position - 0% - EGR valve must be closed. I wish that would have been stated in the instructions from PPEI when I did the delete.
