Is 61.4 psi fuel pressure at idle normal?
I just installed a SPA duel boost/pressure gauge and it reads 61.4 psi fuel pressure at idle with stock injectors and fuel pump (I think, I am the second owner). I thought that 58 psi was normal. Fuel filter was changed about 9k miles ago. Is 61.4 psi in the normal range?

I have 60lb injectors with a Lingenfelter fuel pump, and see 61ish at idle. I've never seen the needle get below 60 infact.

so for stock
Ok so for stock is 60 the normal no matter what you doing? I have noticed that when I get on mine and go WOT, I lose maybe a pound of pressure. The needle slightly dips down. Soon as Iam off it, it returns to around 60. Sound normal? I too run a Cobalt Gauge but with stock injectors and fuel pump. Never changed out the filter nor do I know if the previous owner did. Car has 73,000 on it. Seems to run fine.
