Which to do first?

6fodays · Jan 19, 2016

So i was planning on studding my truck 1 by 1 and then throwing an s472 on the truck and run it on stock fuel until i get my dual hpfp and nozzles. But im having a change in my mind.....since my hpfp is in good shape at the moment and i already have an air dog for a lpfp and ported rails sitting in my room, should i go ahead and throw a dual hpfp and a set of 60% nozzles on to take some strain off of my stock one? Or would it even be okay to run a dual hpfp setup with my stock nozzles until i get a turbo and nozzles? Just trying to save things while i can and not get ahead of myself and avoid having to go back and replace a load of parts.

I know tuning would have a big roll. Could i get it tuned to take the load down on each hpfp to fuel as much as one? But have two for less stress?

What is your end goal and current mods?

Adding dual pumps now is fine, don't even need a tune change really, as it just commands xx PSI, so the pumps would just work less to maintain that.

******d with custom tuning at the moment, but have an air dog and ported rails sitting around. End goal is really up in the air. 800 being a safe point, 900+ when im feeling rich

ported rails have no substantial performance gain and cause surging for some. save yourself the headache and leave them off.

twin pumps on stock nozzles will be fine but again, no performance gain. if you go dual fuel, do the nozzles at the same time.

spooling an S472 on stock fuel is a challenge-really need to drive around the turbo.
