You may want to upgrade your fuel pump as well. TBI pumps are only rated to 15 psi. TPI pumps are rated 30 psi. The fuel pressure regulator will contol it, and run excess back to the tank.

If you want to go that route, the 94-95 7.4 TBI pump is probably the same pump...they changed the injectors and pump on those years, spec is like 26-32 PSI.
