I've read that the fuel trim in double digits it bad, as well as the knock retard I'm seeing. I've seen it hit 6.0 at WOT. This is a gtp with only a custom intake from the thread in this forum. How bad are these numbers I'm seeing? Should I be really concerned? What should I look into fixing to get these numbers better? Fuel filter/o2 sensor?
Thanks as always guys!Screenshot_2013-03-15-19-16-13.jpg
