Does anyone have the low and high side numbers? Any tips or tricks on getting it running in top shape? Houston is about a mile from the sun in mid summer so marginal AC is not an option.
Both air condition system pressures are dependent upon the ambient temperature. You need to locate the correct table Porsche published for your year and model to determine where you need to be.
