Fuel pressure problem?
I have a 2006 C6 A6 with a Vortech supercharger. My fuel pressure gauge have always showed about 70-72psi at idle.
My C6 have been parked for about 3 weeks since the weather have been bad here. I drove it today and I noticed that my fuel pressure guage is now showing 60psi at idle. Can someone tell me why my fuel pressure have dropped 10psi since I last drove it? Thanks in advance.
PS, I don't have a boost a pump since Vortech who installed my supercharger said that I would not need one if I stay with stock 4.5in pulley.
