I have been running the 93 octane tune in my 2013 Challenger SRT8 and started to receive lean codes post catalytic converter. I have changed the O2 sensors spark plugs and done as much diognosic as I could so I decided to take it to the dealer to have them trouble shoot it as they say it might be a pcm issue. Once I put the stock tune back in the lean codes went away but more codes popped up that I have not seen before see picture. Can the tune hold back codes? Also after placeing the stock tune back in it says I need an oil change and I need to service the active suspension system. I am totally confused on why the new codes and that the ones it showed with the tune are no longer there.

the U codes are a loss of communication. Likely means the PCM connectors are not seated properly?

Mike, here are the codes it gave me this morning. Once I took the 93 tune off the lean codes went away. When I started it this morning there was no check engine light but after about 30 miles it came on again. I think you are right about the pcm. Do you have any further insite on to why the lean codes would have went away?

anytime you flash the pcm the codes are cleared.
