Rice Burner

I read the stickys up top, great info. I have diablo and just did some diagnostics because for some reason I have felt that my engine isn't in tip top shape. (i drive it like i stole it far to often)

I did a few WOT and had 0 Knock Retard . Is this possible? I thought everyone had a little bit of this.

Everything else seems normal. I know my air/fuel is out of wack a little but i dont know how to mess with it using predator
