Afm questions
Hey guys I'm getting the code that says afm circuit or afm. I forget which code it is but I know its not the circuit cuz the car has a new engine harness. Should I just replace it back to stock or go o n ahead and get the lexus afm? I want to run higher boost pressure later on which then ill get the 550 injectors and an fpr and afr. All this seems confusing cuz I don't want to install something and have it set wrong and mess something up. I guess all I'm asking for is a little advice and some tips on how to do this right. Thanks
