I'm wondering what my limitations will be on my fuel system? I'm running 11psi right now with a TVS2300 on stock fuel system. How much more can I give it before I need to redo stuff? Thinking of running a smaller pulley with race gas.

 

Are you running all stock fuel system?

 

All stock fuel system except custom fuel rail and 60lb injectors. My truck also has a FPCM.

 

I'd say upgrade the fuel pump to a Walboro 255 for sure. Lets see what others have to say

 

I'm not for sure if I need it? My fuel pump has a variable on demand pump in it now. FPCM controls fuel pump. It runs anywhere from 42psi idling on up to 60 at WOT.

 

I'm good on my stock fuel system at 15 psi until 6300 rpms with no fpr on 93 octane
