Tunning and dealership issues

[ABN45]

So after tuning your truck and then setting it back to stock to say taking it to the dealership for some work on it any issues with the dealership saying it's been tuned or anything like that?

I have an extended warranty on my 2012 Yukon SLT that my dealership thru in as part of a program with Navy Federal Credit Union for Vets.

Don't want anything to come up after I tune and turn off my AFM and then set it back to stock for a dealership fix.

Depending on the scenario, I can't see it as a problem. If it's only AFM shut off, they probably won't even notice. It's not everyday that computer updates need to be done. They look for codes, etc. One thing toggled off probably won't even show up.

 

[OR VietVet]

Does the warranty say you have to take to dealership?

I have taken mine to the dealer more than a few times with a tune installed. no issue they don't even see it.
so unless you are trying to make it go into v4 mode and it has a tune to prevent that then you have nothing to worry about, they don't "check" it
