If you've crawled under the car and verified equal, in-spec tie rod lengths, your bushes and ball joints are all new, and your print-out from the alignment shop shows specs which agree with the manual you have...then I'm out of suggestions and go back to my previous post with questions about wide tyres and potentially wrong wheel offsets.
What are your wheel/tyre specs?
Have you done anything else with the suspension components?
Not saying I know enough to solve the riddle, but it's another place to look if they are way different from stock.
Something else to consider may be a dud shock, or different shock settings side-to-side. Do they bounce the same? Any oil leakage in one?
Or, are the back end bushes etc as fresh as the front? A moving rear end can affect the steering, especially on/off throttle.
A little more information about when you notice the problem may prompt some more advice - over bumps, longitudinal ridges, straight line...etc.
