Default AFPR question

While taking my TPI set-up off for painting I noticed that my fuel pressure regulator looks like it has an adjustment allen screw on it. Not sure if this is correct or does the stock regulator look like this also? The previous owner did not mention this mod when I bought the car so any help would be appreciated.
Thanks

AFPR is a means of tuning the WOT fuel settings w/o having to reprogram the ECM. For fome it is a hack approach to tuning. What more WOT fuel,... increase the FPress. Stock press is 43.5PSI (3BAR).

If you don't know how to tune,.. best not to mess w/ it. At stock press you won't hurt anything.

Cool, a minor mod I don't have to pay for. :thumbs:
ZylaRace, I guess I'll be a hack and take advantage of this when I get my exhaust and injectors done. :D
