This week I installed a fuel pressure sensor for my aeroforce gauge and also to log fuel pressure with hpt.
I have never logged pressure before on this car so I don't really know what's normal. Can someone please explain if what I see is normal.
My understanding is that on a vette like mine the normal pressure is about 58psi. I am getting readings of 62-63 psi which I think might be slightly high due to using a racetronix harness which supplies slightly more voltage than stock. What has me totally confused is that when the dfco activates, my afr goes into the 19's (which I guess is normal), but my fuel pressure goes to 155psi.
Is this somehow normal and what would cause this?
I have not logged fuel pressure on any full throttle runs yet. My car doesn't go lean but I am also wondering what is an acceptable (if any) pressure drop at full throttle. In other words, how much drop would indicate I need to upgrade the system.
Thanks in advance for any responses from the tuning experts.
