Car 'jerks' when gunning it at low rpm

Hi all, I've got a 6 speed, and if I'm cruising around at ~1500-2000 rpm and I gun it in 2nd or higher gear, the car will jerk a couple times then start to go.

If I ease onto the throttle, it'll be fine. If the rpm's are higher, it will not jerk.

Is that normal?

i had same issue... my friend with an 02 ws6 has the same issue. my madz28 tune fixed the "hesitation" in all the gears it would seem. as for what the problem is, i have no idea. i changed a few things including my fuel pump when i was troubleshooting it.
