Hello and welcome!!! Not sure if pulse and glide will work on your car. It usually works well with overmotorized cars and will have no effect on undermotorized cars, which is quite the case of your car.
To me you should accelerate strongly (80% of gas pedal, not flooring) between 2 and 3000rpm when you want to get your speed, and after that anticipate the maximum, use engine brake and not normal brakes (so decelerating earlier).
Your only potential for me is in reducing speed and anticipating.
