your current pump set up will work leave as is no need to over think or re-invent the wheel.
im running 1 DW intake with 1680's and sitting at 595whp on E85 and my Duty cycle is at like 65%. i idle fine with my injectors and i dont even have a IACV installed.
you want good MPG with a good sized turbo you wont be making much of any boost on the street without loading it up so just tune your vacuum section of the map well and watch your foot your MPG should be near stock.
