Figured out even after i switched to "pre gapped" One step colder plugs that the gap still was to high. They were supposed to be gapped to .028 which is .002 more than what the tuner had recommended. So i figured they would be fine to run. Turns out I had a little bit to much trust because the ACTUAL gap of the plugs was .035 HUGE difference. I didn't have the proper tools to gap them down to .026 so I slowly tapped them on a vice and constantly checked the gap until I got all 4 down to .026 or close too. Now she preforms better than ever!
