Yep mine slams hard at 20mph, I make sure I don't hit the throttle around that speed, if so it feels like the trans is coming out. I've done the relearn a few times, to be honesest I'm not sure if it did anything or not, it still shifted hard. The relearn process is by far the hardest my truck has been abused and I feel like I'm tearing it up in the process, I've not done it in the past 15 times I've switched tunes, to me it's too hard on the truck for what it might accomplish, but I seem conservitive to most that run the high hp tunes.
