We generally see injectors maxed out once the car has been modified with full bolt ons including a fuel pump.
Once you start adding more modifications to add power you need an intercooler to keep that air charge cool enough to run efficiently with the rest of you bolt ons. The stock intercooler is just not efficient enough to keep up with a full bolt on car.
