Newb question... Best tuner?
Okay, sorry in advance if this is asked everyday. I did a search and didnt come up with what I was looking for.
What is the best tuner for a duratec? Xcal, x3,? I see those a lot.
My friend just bought one for his F150 and I am hooked. Forget the brand he bought but they only make them for trucks.
Thanks, as always.
