i have a 97rs and i made the Adjustable over boost protector using two diodes and a potentimeter and it works fine but what is the exact voltage a map will count as boost? casue i thought it was 4.7 so i set my AOBE to that and it still bucks , so i moved it down to 4.5V and it is fine now but i would like to set it only like .02 volts away from what it need to be. anyone know?
