Exactly. You cant use any map altering device with stock injects. When you run larger injects, you will get a lot more fuel at each duty cycle percentage over the stock injectors. Eg.. with stock injects at 80% duty cycle, lets say you have 235cc's of fuel flow. With 550cc injects at 80% duty cycle, you have 550cc's of fuel flow. The SMC is basically "expanding" the map sensor voltages to make the ecu run its max duty cycle of 80% or so, at max boost, not at 0 psi. With 440 cc injects, at 0 psi, the SMC will tell the ECU to run them at 40% duty cycle (example only). At 10 psi, the SMC will tell the ECU to run them at 80% duty cycle
