I’ve got an Ez street 600 Fitech fuel injection system. I recently just had to fix my timing, which I think messed with the way my Fitech tuned my truck. Now I have a misfire every time I press on accelerator. Could this be because my timing is still too advanced. Or could it be because my Fitech computer needs to be adjusted?
