[QUOTE="Blown38, post: 12937537, member: 88849"] You need to reference vacuum/boost to the return style fuel pressure regulator. So when it is in boost it will raise the fuel pressure. When you set the static pressure have the car running and unhook the vacuum line from the Fuel pressure regulator and set it to your 50psi then hook the vacuum line back up to the regulator. When you hook the vacuum line back up with the engine idleing the fuel pressure will be lower than your static setting, which is perfectly normal. And for reference ford calibrates injectors at 39.15 psi base pressure. Here is a video [URL="http://www.youtube.com/watch?v=tmKoAVKRY7g"]http://www.youtube.com/watch?v=tmKoAVKRY7g[/URL] [/QUOTE]
