Have a 98 hatch about to swap the ecu and intake possibly injectors also know I have to do the 3 to 2 wire IACV but wondering about injector resistor box I have PL4-1000 RC injectors just wondering if it would be better to run something different to avoid resistor box or all injectors will require it final goal is boosted with around 400hp have intake set up pictured is ported to match the 70mm throttle body ST spring&retainer SF rods Vitara piston and head studs and block guard

 

Check the OHM resistance of each injector... if they measure less than 4 OHM's, then you need to use a resistor box. If the OHM reading is greater than 10, no resistor box is necessary.
