Yeah was going to run 25# injectors and new pump. The 6 lb vortex is designed for the stock 5.0. I believe some of the higher boost require and lift/inline pump also.It's generally cheaper.
I will caution however, most bolt-on SC kits include a Fuel Management Unit and boost pump of some sort. These work pretty well but they're temp fixes. To do it right, you would still get larger injectors, high pressure in-tank fuel pump (or equivalent system), and a tune.
