I would always expect torque-steer to be a fwd phenomenon but I guess with 4WS, it can happen. However, I expect torque steer to be the steering turning to one side but not wobbly?

I appreciate your input as I can learn something.....

We are both learning. I am very curious to learn the root cuase of your trouble.

If it is torque steer (which I am not convinced), the wobble could be due to the IAS system attempting to keep the wheel in line as the torque steer pulls it out. This back and forth struggle (along with your steering input corrections) perhaps creates the wobble.

I also have the JB1 on hand but because I received the TMS first, I had that installed in my car first and JB1 is still lying around in my room somewhere. One thing that I noticed is that the TMS enclosure seems to be a bit larger but of better quality than the JB1. And the adjustable dial on the TMS is a big plus to dial-in the correct boost.......

But now, I am turning the TMS dial down from 6 (shipped) to 3 as I felt that higher boost may need suspension and handling modification so that the car can cope with the additional power.

I have to say BMW did a great job in tuning the 650iGC as everything is very well balanced. As soon as I added boost of power, I started to find little bits and pieces that needs improvement to better handle the additional power.
