i guess i didnt explain that too well. when you add the meth on top of the fuel the motor is already running on, you make the motor rich. you have to lean out the injectors to compensate for the extra fuel provided by the meth. in the end the goal is to have the ideal a/f ratio by getting the correct amount of fuel from the injectors and meth instead of just the injectors alone
