Does the PPE or Predator Raise rail Pressure?

Like the title says do they raise rail pressure? What programmers or modules do raise rail pressure?

No. In fact, the 2nd gen trucks have a problem keeping stock rail pressure sometimes.

i have the ppe hot et2 and on the higher settings you can't run it to hard or else your fuel rail pressure drops of the map and you get a rpm governer but other then that i love the ppe...i increased my fuel economy by almost 4mpg(if driven right)
