I installed a brand new fmu with a 12to1 disk. And when im not in boost or anything fuel pressure is at like 50psi but gets eratic at times. When boost registers though the fuel pressure doesnt increase. But the thing is my car is also bogging in the beginning of gears. And when my car is at idle i can hear what sounds like my fuel pump whining......and its never done that before. Its the stock pump and i KNOW all the vaccum lines are fine. You guys think its that pump craping out or a bad fuel filter making the pump work harder???.....please let me know what you guys think
