Therefore the PPRV is meant to hold pressure in the lines at all times. However there is a thing such as a pprv delete that supercharged or high hp 2v's do in order to release fuel pressure spikes on quick shifts. In that case it would not affect your driveabliliy...the PPRV is in the fuel pump. Are the injectors the exact same size as stock? If not have they been tuned for? There may be a problem with the frps. Or there may be a problem with the fuel pump. But my recommendation to all with fuel problems is to start with a fuel filter. If those are not changed regularly they can pose pressure problems. Good luck and let us know!Sent from my SM-G930V using Tapatalk</blockquote>
