Ok so Ive gotten through my knock retard with fueling situation. But now it seems maybe 3-4 gear shift i get a knock retard to 2.5 degrees and then back to normal. Could this be because of the boken header bolt think i can hear at least on ticking away when i start the car. Im on my phone so cant attach a log at moment but this seems plausable yes? Everything is running great on the truck even pulled timing fuel is right but during that shift point it knocks a little bit.
