its got stock heads and cam and intake , and the mods done to it are in my sig.

You can get away with that but if you are at Sea Level you will work the infectors a bit harder. I would recomend that you run at least 36lb, but if you are planing on putting on better heads and cam then you should look at the 42lb. A GREAT place to get the programable computer for your car and to get even more information is http://tweecer.com

ok well when i get the supercharger im going to get a chip from them and take it to a dyno shop to tune it afteri instal it all, well could i get away with running 42lbs on a mostly stock engine for a few months or what would happen and what is a good fuel pressure regulator tog et and how do i know when its adjusted at where it needs to be?

I would go with that chip if I were you. The main problem with running those is that the computer will start to think that something is wrong and make subtle changes to compensate and after a while you will have to reset the computer by removing the battery for 15 minutes. I recommend going with the Tweecer programable computer. Not only is it the best thing you can get but it is nicely priced at about $500.00.
To answer the other question you can fully adjust the pulsewidth and fuel delivery using the tweecer, but yes you can get away with also. Just be sure to run the pressure as low as you can.

ok but while im adjusting the regulator, how do i know what psi the fuel pressure is at or do i have to adjust it and then hook up the gauge to know everytime?

Mustangkiler

anyone at all?

Just hookup the tester to the test port and leave it attached while you adjust it. I have even left mine attached at times while driving so I know what the max and min pressure is.
