Turn up 7.3 Diesel

There must be a way to trick the computer into letting the fuel pressure come on sooner, in the big truck motors you can adjust the air valve, any way to ajust the MAP?

I don't reccommend any of these, but I've seen people do these in the dealership and swear by them. You can disconnect the MAP and ignore the engine light. If the truck doesn't detect boost, it keeps upping icp and fuel pump duty cycle. I've also seen people put ball bearings (small ones!) in their regulator on the downstream side of the poppet to hold it a little tighter than the spring.
