I also have my misfire tables disable so that wouldn't affect me.

You can raise the misfire count to cure the problem associated with smaller converters. My truck was lean after the install of my dynatechs so....

John is a great guy. I went with a 3900 and when I pull the motor again it will be a 4400. It drives fine even in my heavy pig and really gets some nice 4wd drifts going without nitrous
