I figured it out. My rear driver side wheel was loose. Somehow the shop poorly tightened the bolts when they changed brakes/rotors and when I was turning the RPM was fluctuating all over the place. After the wheel was tightened. it was all good. It was done by Eurocharged Canada. They are awesome by the way. They have own custom tune that amazing!
