Injector tests

[Fergie]

Before I removed the mandates from my 2250 the dealership said I had a misfire in injector 3. Since removing that I haven't had a code pop up. Today I had time to run some tests. First was the leak test in 60 seconds I lost 100psi so good there. I then performed the cutout cylinder test. They all sounded the same. I did both of these tests following Rawze's YouTube video. I then went to the performance test. Got to the third test on cylinder 1 and it stopped claimed I had unstable fuel pressure. Decided to do it again and 1-5 cylinders passed all 4 tests, got to cylinder 6 and it passed tests 1&2 and shutoff. This time it said "The ECM has determined that there are conditions that can damage the engine or prevent the test from functioning properly. The ECM will not start the injector performance test.". Just curious on what to do next. If it's just a glitch in software or if I do have an issue.
