I just done some a/c work on my 2001 formula. I evacuated it and it held 28in vac with no leaks. Since I am relatively new with F bodies. The system took about 2 and 1/2 cans of r-134 and my pressures at idle with a/c on max hi blower were low side at 40 psi and high side about 240 psi and register temp with 92 degrees outside temp in the sun was about 56 degrees and driving the car temps came down to 47 degrees at max and high blower. Can I expect any better out of this system?

outside temps affect the AC discharge temps. usually, you'll get about 20-30* lower than ambient temps. so, looks like it's right inline. getting the low side in the 30-35 psi range will lower the discharge temps a little more.

well said mrr23! 47* on a 92* day is cooool
