355 A/C HVAC Air Flow - What is normal?

Looking for input from other F355 owners on their experience with their air conditioning performance. Particularly how much air flow should one expect to feel from the vents. I am still getting accustomed to my new to me F355 GTS and one thing I've noticed is the air pressure from the vents is very weak. With everything on full blast, I have to hold my hand up a few inches from the vent to actually feel anything coming out. I just had the A/C recharged and that helped a little with the air being colder, but the air flow/pressure is still pretty insignificant. The mechanic says it's just how these are and they're not going to be great.

I am coming from the world of air-cooled Porsches, where my 993 and 964 blow ice cold air and quite strongly too. My F355 is nowhere close to the A/C performance of my 993 and 964. When it's in the 90s and humid in Nashville, the A/C doesn't keep the cabin even slightly cool as I was sweating like crazy. Opening the windows was a better option, and that wasn't great (if y'all know southern heat/humidity, you know my pain). And yes, I know it's a GTS but before you start saying "well take off the top and let the open air cool you down," that just isn't a very comfortable solution when it's treacherous out.

I've tried searching for this issue but I am coming up empty on my results. I've read many positive threads that the F355 A/C is good. Is there something that could be causing my air flow to be restricted?
