I think the vette filter is regulated to 58 psi. I googled some ls1 forums and that is what i came up with .I have checked mine and it is at a steady 54 psi. I have about 6000 miles on mine with no problems so far.
good deal man. I was not trying to say anyone was incorrect, just wanting to make it known that most aftermarket pumps that I have seen support 45psi and it's something that needs to be watched for. I would hate to see someone running lean and melt a motor because they were running lean. Espically over something that could have been avoided
