The first thing you need to tell us is what chassis and ECU you are currently using and what it is programmed for.

You should run the stock narrow band sensor if your car has not been tuned to run without it, so don't unplug it!

A wideband is what you will want to actually tune the vehicle though, so I definitely suggest picking one up, (Innovate MTX-L, AEM UEGO, PLX) are a few good ones.

Ok, then you definitely want to pick up a wideband to monitor the air fuel ratio, especially if you are going to try to adjust the fueling via a SAFC.

The best option for you would be to get your stock DE ecu programed for the VE so you only need to do very minimal adjustments with the SAFC to get it in check.

Tunable ECU should be enough, no need for SAFC or any other piggybacks unless you plan on running NOS.

There are ways to use your narrowband O2 to tune, but it's really for slight adjustments to the stock motor with no serious mods. Get a wideband, it's the best $170-200 you will spend because it can save your motor!

Also if you get a NismoTronic, you can datalog those AFR's in correlation to RPM and TP. That will help a ton too. Otherwise Tuning while driving and starring at the AFR gauge FTL.

You don't really need an adjustable FPR for VE. The only benefit of one is to run 4 bar, which makes your injectors flow more CC. Like 370cc injectors at 4 bar would be about 420cc, etc.

With a NA VE, it would take a lot of mods to max out the stock 333cc injectors.
