i just bought a used vortech V-1 S trim unit for a very good price with 3.33 pulley. its in great condition with no shaft play or leaks. i still need to put some pieces together but its not much. as regarding to fuel, i know i need a 255lp fuel pump and 42lb injectors. do i still need the vortech FMU along with a T-REX pump for "insurance purposes"? what the best maf should i run (lighting maf/80mm) and what psi should the fuel pressure be set with the regulator ? (getting it tuned right away). im new to boost
