I understand that timing will change with the afc hack when getting into boost, but is there a way to lessen the voltage output by the afc toward the MAP sensor?

just an idea i thought of

 

the MAP sensor has 5V all the time

based on pressure readings it will vary from 0-5 Volts signal to the ecu

the VAFC overides the signal going to the ecu to control the fuel amount

theres no need to alter the signal to the MAP sensor since it will compeltely trow off the readings and purpose of the MAP parameter readings
