At idle, with temp about 95 outside, its running about 400. low side about 60. Rev it up and high will peg on the guage, low will drop to about 40 I guess. Other than that, it cools great, seems to Kaleb, Assuming the gauges are accurate, sounds a little overcharged. At 95, I would expect about 40 psi at the suction and maybe 250 high side at idle with the electric fan on. Your evaporator temperature cannot go below the equivalent temperature for any given pressure. Looking at the R134 suction gauge you would observe that for 60PSI, you could only attain 63 degrees, minimum, which might feel nice but is not gonna cut it. Ideally, you want just enough freon in there to hold a steady suction pressure, at speed, just above the cutoff point. too much freon just occupies condenser space and makes it less efficient, resulting in a higher head pressure and higher suction pressure as well.
