2017 gmc sierra 5.3
dod & cam swap. Went with chopacabra. I have codes p0089 and p228d. Ive actually recently got a p0106 which I believe would just be due to it having so much fuel making fuel air ration out of control. I’ve replaced HPFP and Fuel pressure sensor on the rail. Scanner says desired fuel pressure is 580ish which seems low, but it’s getting 1800. Going into engine reduced power. Any tips? Anyone else have similar issue? Low side pressure around 50psi. Could the issue be pcm related?
