Lift pump will help (even on a stock truck), especially if you plan tuning hot tunes. It'll help keep rail pressure and extra filtration is good.

As for tuning, a lot of guys are running EFI live now. A simple H&S will allow you to delete though (I have one up for grabs if you're interested in that route).

A lift pump is going to help the cp4 Live a longer healthier life. Also if you end up going with aggressive tuning, it would be needed to supply the high fuel demands in the tune.
