Just thinking about boost levels, and if there is a leak, how much of a leak is needed before a CEL is thrown? If it's pin sized, there won't be much, but obviously if it's a few mm, then yeah, a large drop will be experienced. But is it thrown if there is a leak, no matter how small? Is it that sensitive?
And if I am losing boost pressure, is the ECU going to make the turbos work harder to reach target boost?
