It does, but I think you refreshed my memory that it is a bypass vs blow off. If it were to blow off MAF would detect irregularity, so it puts it back into the system.

I rarely drive the X that hard but I was shocked myself to hear what sounded like blow off.

There is no blow by from the rings, but it’s a bit rich. That’s why I’m mulling of the idea of reprogramming, because how darn hot it get here during the summer.

I just keep hear an old saying, “leave well enough alone”. LoL..
