new injectors? any ideas

[strokin03]

so i installed an edge evolution in my 2003 superduty powerstroke 6.0 about a month ago. i drove it around for a couple days then returned it to stock so my wife could take it to work. after i removed the programer i drove it to the store and it was running rough. never through a DTC so i didnt kno where to start. so i decided to reflash the ECM. i took it with me to dyno day saturday and bill reflashed it on the spot. i put it back in the truck when i got home and tired it, seemed to do a little better but after it ran for about 30 mins it started surging and then cut off and wouldn't restart. so i plugged the evolution back in to read the DTC and i Got PO271 injector 4 and po277 injector 6, it didnt give me any DTC when i had the old version but showed them when i got computer reflashed.


has anyone had these trouble codes and it been something else. i have already checked the FICM and it had 48 Volts.
