I understand the meaning =regulates fuel pressure,but what are the gains in power.Do you just get em when you need more fuel like a turbo or nos.What if you put one on to close to stock engine??Will it increase performance??Should i buy one used for cheap. I would like to one day get NitrOuS.But will this help me at all??? TIA Chris 94 se-xe razo exhaust/soon to be cat less w/2.25' weapon R intake magnecore 8.5mm wires
