Fuel pressure at WOT

What is ideal fuel pressure at the cp3? Fuel pressure driving around town never goes below 18. When I am WOT it will drop down to 11 or 12 is that okay? My rail pressure is perfect right at 26k all the time. Right now I am running TNT on lvl 5. Just want to make sure it is getting enough fuel.
Thanks

The supply pressures are more then fine but your rail pressure should not be at max all the time. Don't you show different pressures when at idle and low speed cruising?

I meant 26k at WOT all the time. At idle it is around 6 or 7 and crusing is does not go over 20.
