< I have noticed that in temps over 105F, the AC cabin temps climb.>
Yeah, that's about all you can expect. You are maxed out. Live with it.
The only other tweaks are to use a slower blower speed and to Tint Roll the windows.
All other mods are big $$$ items ..
A Note for you and readers:
On the CTS bridging mod, one also has to be concerned with going too extreme with cut-in for fan. The reason for this is b/c that sensor is not just the aux fan control. It is actually the temp Input sensor to the ac Control Module N22, and that module uses that same input sig for compressor cut-off. So , it is possible to go so far that one can get a cycling compresor at high temps, thereby losing a/c capacity...just something to be aware of.
My preference is to run a relay using the low fan feed at the pre-resistor as trigger, and that allows me to have HIGH fan when a/c pressure sw calls for Condenser Fan. That addresses the cond/ac operation directly, and allows for high fan pre coolant temp esculation. You now have High Fan for a/c , regardless of coolant temp. And it is the condenser that drags down the radiator by passive heat exchange at High termal Load conditions...wish they had the condenser mounted somewhere else.
But none are going to ice you out of the car at 105 ambients..maybe fill the back seat with ice cubes ...
