[QUOTE="Phil'scobra, post: 15988250, member: 45850"] Ok, I have an 03 cobra with a 2.3 Whipple, Running stock fuel lines and 60lbs injectors. I have some gauges that are not showing the correct information. I did not install the gauges and I don’t know how old the gauges are but what I have is a standalone Speedhut digital fuel pressure gauge and a standalone innovative A/F gauge and an Aeroforce scan gauge. The fuel gauge and the Aeroforce gauge are reading about 10 psi different, the Speedhut reads 29 psi while the Aero reads 39 psi, Note last week I was driving the car my A/F gauge pegged out at 22.5 and the fuel gauge was reading Sender error. I recalibrated my A/F gauge and now it reads 10-12 when I get on it and 15-17 when it just idling. The car runs fine, no problems, I did have an exhaust leak that I fixed, So, I am not sure what my question is but I would like to know that I am not going to blow my car up next week when I leave for mustang week. What is the normal fuel pressure the cobras see. Also I am running a returnless system. Thanks [/QUOTE]
