the fuel regulator has no part# and does seam to be replaceable. but the pcm still controls the injection and even with 52lb/hr injectors (stock is 27 i believe) the pcm corrects injection. i literally put in injectors from a ford GT40 and a viper, but get better results with those from a nitro R/T (4.0)
