yea bro. I can drive my car as long as I dont boost and keep the rpms down. I started getting this vibration above 3k and the higher the rpms the worse it gets. I pull though 3 gears hard and the vibration was crazy but after decel it was like a loose vibration. I was told it might be my TQ converter braking up but if that was going to brake I would think it would have gone on those hard pulls. Car still shifts and runs fine now. This is why I am thinking a universal joint in the drive line.
