Vintage Air System not too cool????!!!!

New model engines work better at around the 200 mark. I wouldn't worry about that at all. Did you get the fan mod done? Did you try the reprogram on the evap controller? You're duct temp ain't bad, but I'm thinking there is room for improvement. Maybe wait until this silly weather mellows out a bit. Hell, I pulled the back window on my Valiant today and had to jump into the pool to dry off.
