Question about how it works

[mareese90]

I have a successfully got the predator on my 04 ram hemi, I'm new to this and it's Probly a stupid question, will the tune be on my truck still after I've drove it and shut it off, do I have to program it everyday or will if still be there, also when a new update is available will my predator tune disappear? Mainly did the predator tune take place of my factory tune

The new tune replaces the stock tune. It will be there until you write a different tune over it.
