It's not that simple. There are many varying factors in that such as what blower speed your on, what outside temp is, what rpm your engine is at, the condenser fan is 2 speed and will change pressures drastically when high speed kicks in. Dual systems generally run higher on the low side but you should be between 33 and 43 at idle after equelizing. The high side should be between 175 and 275. The current circumstances can vary the pressure. Even being withing these ranges, proper interpretation could spot a problem.
