Also.. Am I suppose to remove my stock fpr or is the car still dependent on that. I did some more reading still not understanding everything but some places I have read said that yes you do need the stock regulator and some say no you dont. The only certanity I have come across was if you had the Vortech SFMU you could totally eliminate the stock regulator. So now my question is do I illimnate it anyway with the craptech? And where is the stock regulator located.
