i have a b16a with super charger it has a reg and gauge i also am running a stock 1.6 vtec sohc fuel pump with t rex from vortec is that the problem i took it off now its at 50 psi when not hooked up do i need that ???

 

If you have an aftermarket FPR then you need to adjust it.

 

with the t rex and stock going at same time its off meter and cant be adjusted but with only stock its at 50 and can be moved 10-15 up or down???? should i run it with out and can i run only trex

 

without it.
