I asked this question in another thread but never received and answer.

What is the minimum and maximum fuel rail pressures that you want to see on the LBZ in order to keep the injectors spraying correctly.

I always try to keep it as high as possible, but I try not to go lower than 24,500. I've never been able to get it to command more than 26,000.
