first i'd like to apologize, since i don't really speak english as good as you guys

i'm experiencing some weird problems with my car. its EUDM 06 IX with TBE and other bolt-ons. however, it has a stock clutch/tranny.

when going from a standstill at 3-4k RPM start (fast, but not as fast as 2 step launch), the car jerks as if something just crashed in its back or if i just ran over a bump. then it starts as it normally would. i swear this wasn't what it is before today.

if i'm trying to set off from lower rpms and a bit more gently - no problems, it goes fine. i would be sure it's a clutch if i had RPM increase before acceleration, or a problem changing gears or something. it's perfectly normal, no strange sounds or anything.

well, does anyone have any ideas?...

To check the clutch you must go on highways and try to accelerate on 5th gear. You'll see if the clutch slips or not.

What about your rpm when this is happenning?

3-4k RPM, standing start. i guess that's what called the peak torque.
i'll definitely try out 5th gear accel tomorrow. but it does appear to hold fine in lower gears..

It's peak torque if you have boost.
In neutral you don't have any boost, so you have no torque except if you have a flash. 3k-4k rpm is too low to lauch the car according to people over there.
