Epson 3800.......Dull output..

Primarily use the Epson luster, RR Ultra Pro Satins...having bought a Colormunki to set up my monitor profile printer...really not satisfied with the output.... the prints seem so dull less vibrant as even my couple hundred dollar Epson R220 dye ink Where can I get a top notch profile made for this printer maybe that will help me out for now. Thanks for your constructive advice.
