Nah I don’t want to drive a ****ty truck.
The PC is a signal amplifier. Nothing else beyond that. There is no feedback from the throttle body or ECU to it so all it sees is how much voltage is getting by and it amplifies that signal to open the throttle body more and to tell the ECU that the pedal is depressed more than you are actually pressing because a difference would throw a CEL.
You push 25% and it tells the ECU and throttle body you are pushing 35%.
I get that this is beyond you because you fell for the marketing but it is simple.
