QUESTION:
Still having problems with insufficient cooling in my house. I had an a/c tech come out and take temps from the room air entering the coil (where the squirrel cage is at) and that air was 80 degrees, he then measured the air exiting the coil and that temp was 51 degrees...can anyone tell me is this coil performing like it should...? (outside temp was 97 degrees and the attic temp was 118 degrees.) After he took these temps he said the coil was fine that my duct work was funky...he said the transitions in my ducts need "triangle shaped duct board" for better air flow...can anyone give me an opinion on this...I've read that duct board really isn't a good substitute for this.... (He used a digital thermo and punched a hole in the top of the air handler and inserted a lengthy wire to get his readings).

ANSWER: Sounds like you have insufficient airflow, number 1 as your temperature drop is too high but according to your last post you are increasing temperature substantially from the time it exits your coil until it enters your living space that means your picking up heat.
Is your ductwork in your attic or crawl space/ basement, it sounds like attic. Is your ductwork properly insulated and is the insulation in tact is your attic ventilated I would investigate these things and post bac. I am guessing you are not moving enough air and the reduced airflow is accounting for the high temperature drop which on the surface sounds like it should be a good thing but it tells me that you are not moving enough air so you can't pick up all the heat your system is designed for.
