Could be clutch woes. I actually broke one of the hub springs in my clutch one time. Really crappy takeoff at normal RPMs.
As far as the bobble strut, they wear out pretty good and the car loses that nice smooth takeoff. I've heard people having excellent luck using adjustable solid bobble struts, but I've never tried one personally.
Check to make sure all the bolts that hold the trans to the engine are tight. Mine did the same thing and 2 bolts were loose allowing the input shaft of the trans to push the disc out of aligment and cause a chatter and not work so great. check the bolts, could be the problemo.
