Golf IV R32 :: While Driving Transmission Lunges

My R32 is a bit higher mileage, around 137k. Over the last year most money spent on the car has been for preventative maintenance and just to make the car ride as best it can. I keep having it happen though where when I shift in a more "Spirited" manner or if I'm in gear giving it gas and then take my foot off the throttle, you can feel the motor/trans still lunge and it's driving me kind of crazy. In the spring, I installed BFI Stage 2 motor/trans/dogbone mounts which have greatly improved everything, however, I still seem to have this movement in shifts/letting off the throttle that I can't seem to pin point. Searching has proved difficult just because of how specific it is I guess, as everything turns up either dealing with the mounts I've replaced or just being completely unrelated.

The mounts are for sure installed and torqued correctly. I had a friend look at the motor while I gave it revs, and the motor does not move much at all, as it shouldn't with the stage 2 mounts. It just seems to be when in motion where if I do a hard shift, there's a lurch and if I take my foot off the throttle while in gear, there's a decent lurch as well. I've driven a buddy's R that has way less mileage and with the same mounts, but there was absolutely no movement like in mine, which just makes me think I'm missing something else.
