It feels like rear wheel steering.
I use accelrator and brakes to turn my cars? Perhaps this is first car you have had with enough power and stick to move with weight transfer?

You may just need to do some suspension tuning to better accomodate the LSD. Tires (amount of stagger) Spring rates, swaybars, damper settings, toe and camber can all impact how your LSD works too. Sounds like LSD is doing exactly what it is supposed to do.

Yeah, I figure its the soft bushings.

Im gonna install my gopro facing the rear wheel and under the car and go drive around, Im curious which contorl arm moves the most.

Me being me I want everything solid to a point so if you can drive, I'm sure things are changing if everything's OEM.

After installing my KAAZ I feel the car changing lines when I accelerate and let go. Not sure if it is just the soft bushes in all the control arms, or something else is up.
When you are in the power, BOTH rear wheels are trying to drive the car equally (and straight ahead at that), and if you have any steering input into the car at that time, the rear tyres are loading the front, so you inhernetly apply a little more steering input to tighten the turn in the direction you are steering.

If you jump out of the gas (abruptly), the car will feel like it "tucks" or "darts" back in and steers more that you;d think - that is just physics as you were applying a tad more steering to cover for the fact that the locked diff is trying to drive the car straight yet you still want it to turn.

If the rear suspension bushes as suspect, the LSD will be loading them as well, so you'll feel some rear steer as well.
