nothing to do with the EGR Deleate itself as far as the CEL
Your PCM is watching EBP and IAT2 for change as EGR Valve opens since it gone theer is no change thus you get a CEL and possibly go into limp mode
I cant get a reading for EBP so my truck PCM not looking for it
Now if I got a Newer PCM stratigy then things might change
03s RULE LOL
If my scangauge cant read ebp does that mean i wont get the 0401 code if i delete my egr cooler and leave my valve plugged in?

P0401 C* Exhaust Gas Recirculation Flow Insufficient Detected EGR Valve Position does not match desired, limits based on
engine speed / load.
EGR Valve stuck or sticking - EGR Valve Position Sensor Bias - EP
Sensor bias.
Your going to need a Custom tune on you SCT tunner for a EGR Deleate and the CEL. Your P0401 is common after the egr deleate
Do you have any other Gauges the Whooose sound is Normaly what we call a Turbo Fart. So how High does BOOST PSI Go????
You can try and clean your EBP Sensor and Tube see if that helps your OverBoost if that what it is
Also need to check MAP&EBP&BARO sensors at KOEO and post Values
How long has it been since the EGR Deleate???
Do you have any Gauges
