codes/performance questions after egr delete/flush and elc

03 6.0 84k miles. Powermax turbo, edge evolution programmer, no cat no muffler, stock exhaust tubes.
Just did the system flush, new oil cooler, egr delete, and elc.
My main concern is that I am now flashing all 8 injector circuit voltage. I have never had any of those codes before. I understand that this could be ficm but my question is why all of the sudden? Truck runs starts drives fantastic. No hint of any injector issues. Also after these mods the tranny is shifting way harder than ever before, to the point that wjen I'm on it is is slamming second gear and lighting up the tires. It used to shift real smooth.

Also I realize the programmer is going to flash the 2 egr codes, but is the some way I can make it stop?

Thanks.

Have you double checked the FICM connector and wires for chafing? It could also be just dumb luck on the P0611 FICM code and the FICM just happen to take a dump. Either way you need to test your FICM.

How long ago did you do the repairs to the truck? When you disconnect your batteries for a period of time, the trans need time to relearn.

It isn't throwing a p0611 ficm code, only the injector codes. I did the flush thur and Friday, never disconnected batteries for any of that. Then i did the oil cooler and egr delete on Saturday. Had batteries unplugged for that from 11am till about 7pm.

As soon as I started the truck after that it flashed 10 dtc codes, all cylinder #1-8 injector circuit low separately and 2 egr codes.

IIRC, when the FICM is on it's way out, it will throw a p0611, or all 8 injector codes, or both. You will need to check your FICM volts and check for wire chafing, bad connection, or broken connector pin(s).

Did you unhook the injector harness during repairs? did you happen to turn the key on while they were unplugged? just thinking out loud if these codes were never there before

We did disconnect all the injector plugs to pull the intake manifold, never turned the key on till we where totally done.

I've cleared the codes 3 or 4 times, but they keep coming back.

ok, well i think i figured out what happened, went to start the truck today and noticed it cranking really slow like the battery was dead.. went to check the alternator and i guess when my buddy put it back on, he didnt completely snap the plug together.. so the truck was running on battery power only. as it was running, i plugged it in, the engine ran smoother/stronger immediatly. I cleared the codes and they haven't come back on again yet.. hopefully that was the problem. thanks for the input guys!
