Im new to using my predator. And im wondering, what do I do to customize the 91 tune to make it run better for my truck? Like I am completely lost.

Then what?

do u have a wide band to check the fuel, also you need to do data logging and check knocking then adjust timing accordingly .

how do you adjust timing? when im idling the knock is around .10, and at WOT it gets up to 2.

I use 91 with the 91 tune. And could it be picking up the noise my alternator is making? I think the main bearing on it is going out cause it used to kinda squeal, but now it just rattles and my charge light is on when i first start it.
