Looking for a little input. Quick run down. Early 04 cr did an engine swap due to needing injectors and blowby from previously dropped valve seat. Swapped in an 03 engine, used all original harness,Ecm, etc. truck fires up fine but can't get rid of 0073 and 0107 codes also get 0483 but truck has thrown that for the last 8 yrs and never been a problem. Feels low on power and boost. No boost leaks, swapped map and iat sensors, cleaned grounds, rail sensor is plugged in correctly. Not having much luck. Searched but nothing has really helped or I'm missing the rite thread. Any input would be greatly appreciated.
