If you're NA, then the only benefit you're going to get from an adjustable fpr is how it looks under your hood.

You could use it to make subtle changes to your afr at WOT, but a SAFC is better for that and besides, do you really need to? I don't know if anybody has done any dyno-tuning of their NA Maxima and experienced any gains.

Stock fuel pressure is 34 PSI at idle and 43 PSI at WOT. This mod would be useless unless you have bigger injectors or a higher flowing fuel pump. But then again, if you had those 2 things, you'd also have boost so it's not even close to being worth it (or useful for that matter) on an N/A max.
