Have some codes
P1280
P0475
P0603
When I did the buzz test I got
P1271
P1272
P1277
When I did the cylinder contribution test I got
P0284
P0541
What do these codes mean, and whats wrong?
My chip is out for a reburn so all of this is without a chip, I have hybrid injectors. At idle my icp pressure is 640, and duty % is 12.4
THANKS

1271 Cylinder #1 High To Low Side Open
1272 Cylinder #2 High To Low Side Open
1277 Cylinder #7 High To Low Side Open
I would check wiring and UVC harness on right bank
1280 Injector Control Pressure Out of Range Low-could be left over from chip if not previously cleared
0541 Intake Air Heater Circuit Low

Are you having any issues other than not having the chip? I wouldn't try to read codes or run tests with any sort of upgraded injectors without getting the tuner adjusted for them and installed on the truck.

I just got the scan gauge and wanted to try it out. After I get the chip back in, I'll run the tests again
