I had the same issue too... off throttle it's pull a little, hit the gas, it'd do the same thing.

I took mine to Custom Alignment in Mountain View, CA (a bit too far for you) and funny thing was, where I had adjusted my coil overs was pretty damn close to what they finalized it at. And then they said: "the dartyness was from your tire pressures; none of the tires were the same psi. they ranged from 19psi to 27psi." They put them all at 28psi and the car was fine all around!

Recently, I started feeling that dartyness again; refilled the tires to equal pressures... bingo!

Check your tire pressure before and after alignment and weight balance.

I believe the race/street bias ply tires (Billboards & TDs) are supposed to be at about 18-20psi.
