Searching revealed that the stock fuel pressure/lbs is 49/23 for a 97' 4.0l, I've acquired some xf2e-c4b which from I've searched is 49/21, how much of a difference is that 2lbs actually going to make? I don't want guesses or "you won't hardly feel it" I would greatly appreciate actual answers and facts about this, will my motor lag, run rough, Use more/less gas to compensate, lower/higher mpg, Or will the PCM fix it and adjust it perfectly?
