The lower carbonation that you taste can either come from the fact that you are used to higher level of carbonation (if you drink a lot of belgium beer for example), or from your setup: make sure that the probe of your temperature controller is not sitting on a cooling line, or too low in your fridge/freezer. Even though I do not use one, a fan could help having a consistent temperature in your fridge. Once you have tried this, you can try increasing the pressure, and see if after a week or two it corresponds more to your taste. Just make sure you have enough beer line to balance this pressure.
