Well, I had the wheels rebalanced and the problem still for the most part remains. However it's difficult to reproduce reliably locally, because there are very few places to get up to speed due to traffic (I live in California). But the few instances that I could get it to come back, it felt slightly different. A little less wobble in the steering wheel, but still apparent from the front right of the car just as always. It happens no matter the curve or straight line, the correlation is that it is always at a certain amount of accelerator pedal going certain speeds.
