I removed the cover from the blower and it doesnt seem that anymore air pressure is at any vents
25 supplys at 6" apiece adds up to (28" x 25= 700 inches of air. But the main is only 8x20= 160 inches. That means the MAIN DUCT is much TOO SMALL to handle this amount of supply takeoffs.
You need a pro to come in and size the supply AND return properly.
