Warmonger (and anyone interested in this topic):

I used my security torx's and removed the module for my MAF and then I simply used a flat-head to remove the backplane on the sampling tube in the MAF (it came off very easily). I then normalized the intake set-up (non-oily/non-saturated K&N, stock svt air-box), pulled the 2 ECM fuses/replaced them, and drove around. Idle in neutral was a bit erratic at times, for a couple sessions, but I havnt had a problem since then -- runs fine. Driving when the engine is in open-loop/cold is still best results but when closed-loop/warm, the engine doesnt buck as badly -- It def. has improved. I am convinced I need the AFC or Greddy to tune-in the needed fuel at lower lvl rpms though to cure this completely. I would be very interested in seeing the results on other 2000/1999 svts/v6's with this problem. WarMonger, you have the 3.0 plus your fuel management and you appear to have cleared up your bucking problem. I think with these "modified" stock MAF's and the AFC/Greddy, the others with bucking can be cured too (looks pretty good). I'll update more as I find out more though my own trial-and-error. Thanks!
