03 blazer 4.3 fuel pressure

[J Shepardson]

Hi guys, I just ran a fuel pressure test/leak down and was hoping I could get some thoughts on my readings.
This is what I got:

Key on @ 58 psi, after the key is on for 3 seconds it drops down to 53 and remains constent, no further drop

Idle @ 50

reving the engine @ 48~58

holding the throttle at 2k (the max it will go) @ 58

Then engine off @ 46 (will hold without loss)

These numbers seem kinda low to me, any thoughts?
Thank you
