Looking into getting one for upping the fuel pressure on my MPI. Modifications so far are Stage 4 head, Fast road cam, 52mm throttle body, ported & polished inlet manifold, stage 2 LCB downpipe, and probably a few others I’m forgetting. Minisport say they are a ‘necessity for getting the full power potential from a modified MPI’ any truth to this?

general consensus not worth it.

 

if you are running out of fuel then an adjustable regulator along with an uprated pump would make sense but just a regulator all it does is control the fuel pressure to the injectors but does not increase the fuel to them.

Few points - don't be taken in by 'stages' it's a sliding scale of nonsense with no standardisation between tuners apart from stage 1. What 'fast road cam?' as that doesn't mean much without duration. A polished inlet will be detrimental for air/fuel mixing prior to entering the cylinder head as it removes the tumbling effect of the flow. Don't believe anything those jockies at MiniSport say.
