Hey Korey, the LML is ok for a stock truck. Larry likes his and has 6500miles on it without putting any urea in it yet. FYI, we have Urea on the shelf guys for those of you that have already gotten an 11. I personally would keep the LBZ, I think the airbox may be screwing with your tunes. After the first of the year get with me and we will get it looked at bud.
