Derate and 20 psi boost due to EGR short or voltage below normal

[Redland1]

Had my truck go into a derate about an hour ago.Boost is 20 psi max.I’m wondering if I demandate it will the derate go away? I know it’s not the proper solution but I just started a new gig after being down a couple of months unrelated to the truck and if I take it to the shop I this soon after starting I lose my spot. The intake manifold pressure sensor code has been there for a while and was still boosting 40 psi before the egr codes popped up.
