1st timer: bigger injectors in a nissan

[Stephen Andersen]

This may be inconsistent with the purposes of this list,
but the application of an Apexi S-AFC or HKS Super AFR
will allow you to "adjust" the MAF sensor output to allow 
you to compensate for the upsized injectors.  These units
run 300-400 bux and provide a lot of adjustability.

Used quite widely in certain circles for tuning highly
modified OEM turbo'd cars.
