Re: Boost solenoid diode

The diode is for spike in voltage that can cause irratic ecu glitches but it shouldnt make it over boost in those gears. I've been running boost by gear for a few years with s300 and no diode, works just fine. maybe your intake temp corrections or duty vs pressure table need to be adjusted, or maybe its just boost creep and you need to make adjustments to the tables accordingly
