How to Clear Tune and Reset Car to Factory Settings
Got a used 2016 ss. Dealer said it had an HP Tune on it. I'd like to clear the tune and reset the vehicle back to factory settings. How do I do that?

Does the engine have any modifications (e85 flex fuel, cam, headers, etc.) that would require the modified tune?

Then you don't want to flash the tune back to stock unless you put factory headers back on it.

Adding to Kings comment, If you flash it to stock with headers your will generate 420/430 cat codes at a minimum and then eventually some more. These codes will get stuck in ECU and will not clear (unless you flash it again with factory GM software) Ultimately, if you flash it to stock, the car needs to be stock unless you have something that won't affect the tune like a cat back or air filter upgrade,
