It sounds like your right rear tire is getting more traction than the left. When you accelerate the rear end torques clockwise, if your looking from the rear of the car. This applies more force on the right rear. You would think with the weight of the driver it would equalities the force on both tires. It does not. If you can adjust your rear shocks, increase on the right and decrease on the left. You can play with the tire pressure but it hard to keep it where you want it. The change in tire temperature and weather will change the tire pressure. I had to install adjustable coil overs to cure mine. Soften the spring load on the drivers side and increase the spring load on the other side. You're shifting some of the power from the left wheel to the drivers side. To much and you will pull to the right.
