Nippondenso Fuel Pump help injector output?
Mods in Sig: Was cruising last night and I don't have my profec-b spec2 installed yet but it's in the garage, anyway, so I've been taking it lite and trying not to overboost by hauling ***. I decided last night to just punch it real quick from 4500rpm in 3rd and got a PFC reading like this: Boost = 0.85bars (like 12.5psi) and Injector Duty = 85.5%!! The injector duty kinda scared me. My question is, I have a Nippondenso Fuel Pump on order from the rx7store and was wondering if when I install it will that bring the injector duty down any or do I need to go ahead and put some 850s in as my primaries? Thanks

It is possible to get a pump which is powerful enough to overpower the stock FPR.

.85 bar on the PFC commander is more like 13 psi in reality. Get a separate and good boost gauge.
I would not want to go over 90% injector duty. The fuel pump will do nothing for you until you install larger injectors.

It has nothing to do with the metric conversion, the Commander displays a low boost reading, the higher the boost, the less accurate it is. This is a well known problem with the PFC.
You only need bigger injectors if you want to raise the boost above what you are currently running.
