I traded my 13 Mustang GT (which I learned/tuned with HP tuners) for a new 2019 C7 Stingray.
I started reading this forum again and I see posts about 'locked' tune.
Can someone clarify for me:
- Is it even possible for me to write to this ECU with HP tuners?
- What else besides GM credits do I need to be able to write to this ECU?
I eventually want to add headers and cam and want to be able to tune for that.
Thanks so much for any direction here.
