I bought my 13 GT500 with some performance parts and an unknown tune. I've since taken it to a local performance shop and had a custom Dyno tune put onto the car. After I use my SCT X4 to take my custom tune off and revert it back to this "unknown" tune. How do I reflash it to the factory...
Also selling my ID1300X injectors, still in the car. Will be taken out Saturday. Car has been sitting since I'm selling it. $1500 plus shipping. 300 miles on them.
**No longer looking for injectors, thanks.
