I have read many posts about people having problems with low fuel rail pressure. I haven't heard anyone say their rail pressure is too high. So my questions for the tuners and builders out there is this;

1.) What is a desirable rail pressure?
2.) What is considered too low of a rail pressure?
3.) What is considered too high of a rail pressure?
4.) What problems would high rail pressure cause?
5.) What should it be at idle vs partial throttle vs full throttle?

Any one with a rail pressure gauges let me know what you are reading in various conditions.

If your answer is dependant on the motor and its use, then use the truck in my signature, '05 LLY, Daily Driver, single turbo, stock sticks.
