Not at all! When trying to give the car just a bit of throttle, like in parking lots or cruising, It likes to do a weird hesitate/lurch thing. It's really annoying, but it's done that since I modded it. When it was stock is the only time it hasn't done so. Meh.

After my last post, I made a slight change in my setup. Not sure if this will help you, but maybe it will help someone! After researching this a little bit further, I read a few posts that suggested running a line directly from my Tial BOV to the intake manifold. I still had my "hard line" setup on the engine cover, and at the advice of Tial, I went ahead and purchased some 1/4" vacuum line. Sure enough, after removing the hardline and replacing with the vacuum line, I can say that a LOT of my low RPM/ Low speed buck is gone. It's a night and day difference. At first I thought I was imaging it, how could this affect that?? But after more than a few trips with my speed going down to as low as 5-10 mph (which would normally cause some pretty sever jerking), I can report that it just feels so much smoother.
Hopefully this helps someone, I'm not sure why I waited so long to do this!
Nice heads up, though. Thanks!

Edit:
Also, the tables I am playing with are the ones under the Idle section. The tables they talk about in the first few pages of the disassembly thread are under ISCV control. For my ROM these tables are in % demand. I feel like steps position for the idle table is probably more correct?
