Coming from a mechanics perspective, I don't see how that is even possible! The Jb4 needs to communicate with that sensor in order to read if the motor is boosting or not. When it reads that it allows the ecu to compensate for timing and fuel, along with your 02 sensors. I can get more technical but this is more easier to understand. Is there any way you could forward me that information about the MAF, and that update?
