Ecutek uses your factory calibration (or the cal id it has after bm3 changes back to stock for those switching).

It's the first step when unlocking is to check the factory cal id.

Regardless, an Ecutek tune done by Bend Calibration is my recommendation. They have absolutely transformed my car into the smoothest running setup with their bend anti-kangaroo throttle mapping and their completely custom boost control. Add this to the best flex fuel setup (they were truly one of the first to do flex properly on this platform). I could go on but feel free to do your own research.
