if your engine is everything in stock ..its not neccesarry to install a adjustable fuel regulator in...use back stock FR is sufficient enough ... for those heavy modded engine ... they can't use back the stock FR ...they need AFR to tune the best psi for their modded engine ...(correct me if im wrong ..sifus out there)
Juz giving my opinion base on my previous own theads which all the sifus telling me that ...or maybe im wrong xD
