Mostly what you'll see with a boost leak that's big enough to hurt the turbo
is a slower response time with regards to that isn't always as apparent in
the seat of your pants as it is at the gauge. In my case I tie into the
divertor valve signal line... when there's crap for vacuum at idle (because
it's all leaking past), I know a divertor valve is toast...
