How much fuel pressure do i need to be running with my mods. How can I install a gauge to tell me what my fuel pressure is?

If that's it don't mess with the FP. You could adjust it a little but you probably won't feel any difference. From what I've learned, TBI fuel pressure is set and forget, TPI responds much differently to fuel pressure. When you make 50hp more than stock it might be a good idea to change the injectors to #55. Then if you go more you should look into chip programming to change the fuel curve etc.
