Fuel pressures within limits?
Hi all, I have a 2002 Z with an stock 430hp LS3, stock fuel pump/injectors. My question is at ignition ON fuel pressure is at 58psi and engine running its 66 psi. Will this affect my tune or cause any other troubles? It is a track car only so it lives at hi revs, THX!

No return line in fuel system, as all emissions have been removed. Im not sure why it reads 66psi, its a OEM fuelfilter/regulator that was changed about a year ago, unless I got a dud.
I did put the old alternator (LS6 2002) back on as I had the 2008 LS3 alt on there. Not sure if that would change anything, but they do look a little different. THX!
