My car had the same symptoms: poor cooling at low speeds and system pressure way too high (over 30 bar: sorry, i don't know how to convert this to psi). It turned out that the pressure switch was bad. This switch controls the operation of the cooling fan. When pressure rises over 16 bar, it should turn on the fan and when it falls under 12 bar, it switches off the fan. Obviously these are pressures on the high side. You can check fan operation when the engine is cold: let the engine idle and turn on AC (ACC at LO setting), check fan operation. It should switch on for let's say 20 seconds and then switch off for a minute or so, then on again and so on. With hot engine the engine temperture sensor interferes by turning on the fan.
good luck!
