I bought some gauges today and here is the outcome. Those readings are pretty good aren't they? Ambient temp was 108

That would be good at 85-90 out side. At 105 it shows 50-55 low and 330-335 high. At 110 it shows 50-55 low and 340-345 high.

This a site has an ambient temp Vs. pressure chart. I use that for reference if I don't have spec.

That is where I looked for correct readings. Is every site different, or is this site just wrong?

Wow. What a difference. I will have to look when I get on my computer. I'm on my cell right now.

Either way, it still must be a mechanical issue since both the low and high are in line. Even if the readings are low, wouldn't that just mean it needs refrigerant. If it is low, its not to the point where the compressor cycles on and off. So I'm kind of confused on where to look now.

Did you mess with the settings in the tune???

I think I just added some airflow but that was it. Why?

I can post the tune if you would like. I use HP Tuners

I was just curious if maybe the Settings for High temp were messed with. Sorry I have EFI live. Been a while since I even looked at what was in there for AC settings.

There are just a few airflow tables and some delay/decay tables for when the compressor engages and disengages. There aren't any pressure settings.

here is were I was getting the specs from that I quoted earlier.
IDQ - Auto A/C Products & Sealing Solutions

I am still wondering if there is an issue with the compressor.

The system must have been over pressurized to vent the pressure. The question is why???

Did you install E-fans??? If so were did you get the settings from???
