if he thinks you're going to need double pumps for 350-400, he must be running you REALLLLL rich.

Only need dual pumps if you plan on running E85. A single DW301 and in most cases even a single Walbro 255 should flow fine up to about 500whp on pump gas with a return system. As for injectors, to be honest, again on pump gas, you should be goo with about 700's up to the 400 range, however Im selling my 1000's for a steal, if you're interested pm me - Im asking $275 shipped for the set

I made 309 whp on a mustang dyno with a custom return setup, 700cc Deatchwerks injectors and Walboro 255LPH fuel pump. A single pump setup will get you there easily just need a higher flow pump, return fuel system, and modified fuel pump housing. If the person that is suppose to be doing this told you need dual pumps for 350-400 then I would not use him to do your build he obviously knows nothing about the tC or understands the fuel requirements.

With e injectors you have plus the fuel pump all you'll need is a fuel return setup and you'll be good to go. I have a walboro 255

Yes you should be good as long as you have a return fuel setup.
