Oh wow, they come with Holley dominators and an engine harness. That’s actually a really good selling point. I’m not sure if it’s possible with the dominators but do you guys lock the tune file, or do you let the owners have at it with a caveat?
They're left unlocked so users can adjust them as needed (we recommend professional assistance with this) as occasionally someone with say a heavy car, or a highway gears, etc, may need minor adjustments.
