fyi, I have APR snub, 2.8 engine mounts, stock tranny mounts, no DTS = NO off throttle jerk.

im tending to think this problem that some of you have is engine related, perhaps BPV/PCV.

what bpv do you have. I've been running a PES (TurboXS) one for 3yrs which I think is adjustable...

but not sure what kind of adjustment I would need to do.

by "jerks" you mean back and forth or just back ...cause I thought the "jerk back"

was normal especially in 1st and 2nd as the engine braking is insane in those gears...?

i logged off, but you can see there are some well based responses

I have had similar jerky experiences... and it was due to the BPV. If it doesnt open fast enough the engine will react very unhappily.

I would say try a 710N and see if the behavior is improved, or try adjusting your GFB

Well...my car has the same exact problem that he described....yet I run a DV.

It has sort of a "buck" when I let off the gas in lower gears...especially when driving slowly. In my 2000 A4 this was solved with a DTS bar and snub. With my 98...I cant seem to solve it...even with RS4 engine mounts/trans mount, DTS, and a snub mount.

I have run the GFB hybrid valve in my cars before with great success. Even when running a true BOV (100% vent) I would only get a little throttle bobing at idle...never crazy jerking when letting of the throttle.
