Cal ID 68054009AD

[SoulChallenger]

I have a 2010 Challenger R/T 6spd. Im using the Predator U7135, with version: v.9r28 This is not working for my car. My Cal ID is: 68054009AD. Asking me to downgrade. Is there an update soon for this?

Damn. I also have a 2010 Challenger R/T 6spd. I thought my Cal ID was 68043009AD but instead it is actually 68054009AD. I thought for sure I would be able to tune with the new u7135-9r28.crom. Guess I will continue to wait........

I also have the U7135-9r28.crom. When I plug it into my 2009 Charger SRT8 I get a message saying "Your current calibration is 68004302AF and needs to be downgraded to 68004302AD". Then I can either select DISAGREE or AGREE. I haven't selected AGREE yet, but when I select DISAGREE it says that my current calibration is not compatable with the tool and shows me my calibration #68004302AF.

Now, keep in mind, I recently had my car into the dealership for service and they reflashed my PCM with the Diablosport tune in it... I called Diablosport yesterday and they reset my tool over the phone and then I upgraded to 9r28. Ever since my car was reflashed, I have been getting this message. resetting the tool didn't help.

Help!!!

You can downgrade your Cal ID if you choose to. I did on my 2010 RT and just updated back to my original Cal ID with the 9R28 update. You can find dozens of posts on this forum about the pros and cons of doing this. I wanted the performance improvements the Predator brings to the table and downgraded my CAL ID back in July. I would do it again in a minute. Your mileage may vary...

Hi, thanks for the response. What are my options if I don't want to downgrade? Do I have to wait until the next tune release comes out? (9r29?)
