I have a 2002 mustang gt with a vortech.. It has been tuned, but its starting to mis while normal driving.. Could it be cause its not getting enough fuel.. What fuel pressure should I have at idle?

36-38 psi at idle

So since my gauge is reading 20psi at idle then I have problems?

yea there is a good chance you have problems if its that low. I wouldnt be able to tell you what it is though maybe one of the fuel system guru's chime in.

the car runs good at idle and seems to have power, but it has a hesitation when normal driving.

my fuel pressure isnt that low but I get a slight hesitation sometimes when im just caostin'. a member on a different forum siad its something thats called maf wash that commonly happens when you have a centri blower and a braw thru maf setup instead of a blow thru. If you have a blow thru already and you are having that issue then i have no idea. but if you have a draw through set up try looking up maf wash and see if thats similar to what you are feeling.

My car runs ballpark 30psi on idle, 40-42psi in boost.

disregard previous post, you have a returnless system.
