Is a SARD rrfpr nessecary with an Apexi Ecu and wideband?

[garrygt]

As above, I bought a rrfpr when I was plannin going ct9 hybrid, since then have gone fully forged and planning a td04. Do I need this or would I be aswell selling it?

An adjustable FPR is always a good component to have as it allows the tuner to maximise the injector flow rate without having to upgrade to a larger injector size. Keep it mate
