[N.E.R.D.]

Does anybody make throttle bodies for OBD II VR6's. If so, how beneficial are they, what type of gains can be seen from this modification? Info information will be helpful. Thanks.

With OBD II there have been proven bucking and drivability issues with this over and over again. The OBD II TB is pretty damn big to start out with, I would look elsewhere for more power. If you where an OBD I it would be a whole other story...

Nah they dont make them, but if possible you could try a OBD-2 2.9 Euro T/B which I could tell you is EXTREMLY hard to find

I see on giacusa.com that they were the first to resolve the bucking issue with OBDII TB, is he talking about the stock TB?
