What should be the stock fuel line pressure for the newer models ?

Since I know that the older one's were between 58-61, and have been currently getting 46 on the fuel pressure gauge, even with an upgraded fuel pump.

Its a 5.3 1500 Seirra, the engine has been swapped to a l92 418 ci, with a 14psi d1sc Procharger, and a 4l80e lvl 5 Flt tranny.

I'll be uploading a video of the car idling later today.

Thanks.
