Have AVC-R? Need an S-AFC?

[T0nyGTSt]

I have an AVC-R. I barely understand what it does (boost controller?).

Do I need an S-AFC? And where may I buy one and how much?

AVC-R is a boost controller, S-AFC allows you to adjust the fuel maps ie if your running to rich (too much fuel) or too lean (too much oxygen). You can buy them from Unique autosports (www.nismo.com.au) or perfect run (www.perfectrun.com.au) or negun (don't remember the website) for around $600
