those with the Af/x UDP...I just installed it today and the car seemed a lil hesitant than before in throttle response. Does it take time for the car to adjust to the pulley or did I do something wrong with the installation.

mine didn't have any problems besides eatin a belt within 2 days....ever since its been fine so I don't know.....no hes. tho

Your car shouldn't take time to adjust, it should spin easier for multiple reasons. I doubt you did something wrong, all it does is drive your accessories, more or less fool proof. There's probably something else causing it that's more noticeable now because you're paying more attention to the motor.
