This is just a guess but do you have any sort of intake or throttle body or even an o/r pipe on your car? I know you had said you tuned for a stock intake. It sounds like something is causing it to run rich. Again, I'm no expert and I'm not sure what the problem actually is, but send the log over to Steeda and make sure they have you tuned for a stock intake and whatever else. That could easily be the cause of it. Small chance it is though, really don't think Steeda would have an oversight like that. Let us know what it is! I'm curious.
