No muffler equals low injector control sensor pressure?

I recently cut off the catalytic converter and muffler off of my 04 6.0L diesel, shortly after my check engine light comes on. The code was, I believe, low injector control sensor pressure. Could the lack of muffler and cat be causing this? The truck will get a burst of fuel and buck occasionally. Any help is appreciated. Thanks.

Opening the exhaust shouldn't make that happen.

Does the sensor need replaced or something else need adjusted?

Not related to your exhaust. It is a high pressure oil problem. Maybe ICP sensor is bad but it could also be a bad IPR or a HPO leak.
