I should also mention that this past thursday night I kicked the a/c on driving home (dark out, ambient temp of about 80). 12 miles total and the A/C dropped to 44 with the a/c set on recirc.
I am convinced my a/c charge is correct but I guess it cant hurt to add more which I'll do tomorrow, but I think it has to do with my 21 row setrab oil cooler kit that pretty much blocks the entire a/c condenser fan. I feel like the condenser fan is just pulling all the hot air off the oil cooler and throwing it into the condenser. But shouldnt that logic also mean the car shouldnt cool when its dark out/low ambient temps?
