I am not sure at all what the timing or fuel were at with that plug. I will be getting new plugs when all is ready to go with the new cam. Since it is so easy to change the tune during a dyno test, what changes would you like to see for that test. I will make a few tunes to prep for that.
Not necessarily changes but more so actual tuning. Making runs at different wot timing and seeing what the engine responds to. If your tuner or dyno operator are not doing that they are not doing you any favors.
