Keep in mind Jwick that most if not all tuners turn off the misfire code. So if one cylinder is misfiring you wouldn't otherwise know it. When I turn on my launch control I cut fuel so that cylinders misfire, the with that code off thinks everything is just fine.

Mine isn't turned off. JTran just reduced the sensitivity of the random misfire portion below 1500rpms. I haven't had that code pop up since he adjusted it. The rest of the misfire codes are still OEM settings.
