If you run the DCCD in any other position besides auto does it still do it? Try it in each setting.

If your running Launch control/ FF shifting you can get a "bucking" when your feathering the clutch for the next gear at RPM's that are higher than the FF shifting Limiter.

But usually its because I let the clutch out too early, which for a moment pushes the motor to the slowing down side of things, then it kicks back to the loaded side.. if THAT makes any sense..

That's exactly hat it is. You have to get on the gas early with DBW.

My vote is on Launch Control too. I had the exact same problem until I moved the LC rev limit up to redline.(my protune map had LC built it)

I forgot to raise the limiter for my FFS with the LC map after I disconnected my battery and it did this and I almost **** bricks. You can go to Cobb's website to see how to adjust the FFS and LC limiters.

Mine used to buck when the ring lands were blown. Do a compression test now! You don't want pieces of piston coming out of the engine and going into your turbo. (not like that happened to me or anything!)

engine mounts maybe?? I wrote a long review on the group-n's i got put in...i hated the bucking when i went on/off throttle. And it wasn't just a first gear thing either. There's a lot of engine movement over the stock mounts.

Check out my review - do a search under my name in this section, should come up pretty quickly.

Let me know if you have any other questions.

p.s. I wouldn't jump to the conclusions that interior flaire did quite so soon

I don't think its something quite that serious.
